Vegan Chickpea Tuna Salad

Last summer, I was hunting for something that felt like lunch but didn't weigh me down before an afternoon hike. A friend casually mentioned her chickpea salad tucked into cucumber halves, and I remember thinking it sounded almost too simple to matter. The first time I made it, the kitchen smelled bright and vinegary from the pickles and mustard, and something about how the cold, crisp cucumbers held that zesty, creamy filling made it feel elegant despite taking barely twenty minutes. It's become my go-to when I want something that tastes like care without the fuss.

I brought these to a potluck last spring, worried they'd be overlooked next to heavier casseroles, but people kept coming back asking what was in the green boats on the platter. Someone's daughter, who'd been skeptical about vegan food, ate three and didn't realize there was no fish involved until halfway through the conversation. That moment stuck with me because it showed how this dish doesn't apologize for what it is—it just tastes good, and that's enough.

Ingredients

• Chickpeas (15 oz can, drained and rinsed): These little legumes are your protein anchor, and rinsing them well removes the starchy liquid that would make your filling gluey instead of creamy.
• Vegan mayonnaise (2 tablespoons): This is what makes the salad binding and luxurious; don't skip it or substitute with oil, as the emulsion matters more than you'd think.
• Dijon mustard (1 tablespoon): This brings a sharp, sophisticated note that prevents the whole thing from tasting flat or one-dimensional.
• Lemon juice (1 tablespoon): Acid brightens everything and adds freshness that makes you feel like you're eating something vibrant rather than heavy.
• Red onion, finely chopped (2 tablespoons): The bite of raw red onion cuts through richness and adds a peppery quality you won't find in white onion.
• Celery, finely chopped (2 tablespoons): Celery brings a subtle crunch and herbal undertone that tuna salad traditionally relies on.
• Dill pickles, finely chopped (2 tablespoons): These are not optional if you want authenticity; they add umami and a pickled brightness that makes this taste like the real thing.
• Fresh dill, chopped (1 tablespoon or 1 teaspoon dried): Dill is the secret thread connecting everything; fresh is noticeably better but dried works in a pinch.
• Capers, drained and chopped (1 teaspoon, optional): If you love briny, complex flavors, capers are worth tracking down because they add a sophistication that feels special.
• Garlic powder (1/2 teaspoon): This ensures every bite has depth without the sharpness of fresh garlic overwhelming the delicate filling.
• Sea salt and black pepper (1/4 teaspoon each, or to taste): Taste as you go because the pickles and capers already contribute salt, and it's easy to oversalto.
• English cucumbers (2 large): These are longer, thinner, and have fewer seeds than regular cucumbers, making them ideal boats that hold their shape without crumbling.

Instructions

Mash the chickpeas with texture:

Pour your drained chickpeas into a medium bowl and use a fork or potato masher to break them down until they're mostly rough and chunky but not completely smooth. You want some chickpeas to stay whole so each bite has varied texture, not a uniform paste.

Build the salad with intention:

Add the vegan mayo, mustard, lemon juice, red onion, celery, pickles, dill, capers, garlic powder, salt, and pepper all at once, then fold everything together gently until just combined. The mayo should coat everything evenly without you overmixing, which can make the filling too dense.

Taste and trust your palate:

Take a spoon and taste the filling plain before moving forward; this is your chance to adjust seasoning without second-guessing later. Add a pinch more salt or a squeeze of lemon if something feels flat or one-note.

Prep your cucumber boats:

Wash the English cucumbers under cool water, then place them on a cutting board and slice each one in half lengthwise with a sharp knife using one smooth motion. The longer shape means you get elegant, stable boats rather than round discs that wobble.

Hollow out without tearing:

Using a small spoon, gently scoop out the seeds and soft center from each cucumber half, working carefully to leave about a quarter-inch of flesh on all sides. If you scrape too hard, the cucumber will split; if you leave too much flesh, the boats will be awkward and heavy.

Dry and stabilize:

Pat the insides of your cucumber boats with a clean paper towel to remove excess moisture, which prevents the filling from sliding around. A dry surface also helps the salad stay where you put it instead of weeping liquid as it sits.

Fill with confidence:

Spoon the chickpea salad into each cucumber boat, using the back of the spoon to gently press the filling down so it nestles snugly into the hollow. Don't overstuff; the filling should mound slightly but not spill over, keeping the whole thing elegant and easy to eat.

Serve fresh or chill strategically:

These are best served immediately while the cucumbers are crisp and the filling is cold and bright, but you can refrigerate them for up to two hours if you're planning ahead. Beyond that, the cucumbers start to weep slightly and lose their snap.

There's something almost meditative about preparing these—the quiet rhythm of chopping dill and pickles, the cool feel of the cucumbers in your hands, the smell of mustard and lemon mixing together. By the time you're filling the boats, you realize you've made something that looks like it took real effort but required almost no skill, just intention and good ingredients.

Why This Works as a Vegan Tuna Salad

Chickpeas have a meaty texture when partially mashed that mimics flaked tuna in a way tofu or other proteins can't quite achieve. The combination of dill pickles, capers, and mustard are the exact same flavors that define classic tuna salad, so your brain recognizes the taste profile even though the protein source is completely different. That familiarity is what makes this feel satisfying and complete rather than like a substitute or apology.

Timing and Make-Ahead Strategy

You can make the chickpea salad up to a day ahead and store it in an airtight container in the refrigerator, which actually helps the flavors meld and deepen. Prepare your cucumber boats no more than a few hours before eating to avoid them softening and releasing too much water. If you're bringing these somewhere, pack the filling and boats separately and assemble right before serving for maximum crispness.

Customization Without Losing the Soul

The beauty of this dish is that it's flexible enough to bend toward what you have on hand or what your taste buds are craving that day. You can swap the vegan mayo for plain unsweetened non-dairy yogurt if you want something lighter and slightly tangy, or add a teaspoon of sriracha if you're in the mood for heat. Top with sliced radishes for peppery crunch, green onions for allium sharpness, or a whisper of smoked paprika for visual warmth and subtle depth.

• Fresh dill can be replaced with tarragon or chives if that's what's living in your garden or fridge.
• If you can't find dill pickles, use any tangy pickle chopped fine, or substitute with a teaspoon of pickle relish.
• These work equally well stuffed into avocado halves, whole tomatoes, or even scooped onto crackers if you want to play with the format.

This has become my summer answer to the question of what to bring to gatherings when you want to contribute something nourishing that doesn't require heating or complex logistics. It's proof that vegan food doesn't need to be complicated or apologetic—just thoughtful and honest.
