# What You'll Need:
→ Bread & Cheese
01 - 4 slices hearty sourdough or white sandwich bread
02 - 4 slices sharp cheddar cheese (approximately 4.2 oz)
03 - 2 slices Monterey Jack cheese (optional, approximately 2.1 oz)
→ Sriracha Mayo
04 - 3 tablespoons mayonnaise
05 - 1 to 1.5 tablespoons sriracha sauce, adjusted to taste
06 - 1 teaspoon fresh lime juice
→ Butter
07 - 2 tablespoons unsalted butter, softened
# How to Make It:
01 - In a small bowl, combine mayonnaise, sriracha sauce, and lime juice until smooth. Adjust the sriracha quantity to reach preferred heat.
02 - Spread a thin layer of softened butter on one side of each bread slice; these sides will form the exterior of the sandwiches.
03 - Place cheddar and Monterey Jack cheese evenly on the unbuttered side of two bread slices. Cover with the remaining bread slices, buttered side facing outward, forming two sandwiches.
04 - Spread a generous layer of the prepared sriracha mayo onto the buttered (outer) side of each sandwich.
05 - Heat a nonstick skillet or griddle over medium-low heat.
06 - Place sandwiches mayo-side down onto the skillet. While the first side cooks, spread sriracha mayo on the remaining top side of each sandwich.
07 - Grill sandwiches for 3 to 4 minutes per side, applying gentle pressure with a spatula, until bread achieves a golden-brown crust and cheese is fully melted.
08 - Remove sandwiches from heat and let rest for 1 minute. Slice and serve warm.
