# What You'll Need:
→ Bread & Cheese
01 - 4 slices hearty sourdough or white sandwich bread
02 - 4 slices (4.2 oz) sharp cheddar cheese
03 - 2 slices (2.1 oz) Monterey Jack cheese (optional)

# How to Make It:
01 - Combine mayonnaise, sriracha sauce, and lime juice in a small bowl, mixing until smooth. Adjust sriracha to desired heat level.

03 - On the unbuttered side of two slices, distribute cheddar and optional Monterey Jack cheese evenly.
04 - Place remaining bread slices on top, buttered sides outward, creating two sandwiches.
05 - Spread a generous layer of sriracha mayo on the buttered side of each sandwich.
06 - Heat a nonstick skillet or griddle over medium-low heat.
07 - Place sandwiches mayo side down in skillet. While cooking first side, spread sriracha mayo on the remaining top sides.
08 - Grill each side for 3 to 4 minutes, pressing gently with a spatula, until bread is golden and cheese fully melted.
09 - Remove sandwiches from heat, let rest for 1 minute, then slice and serve warm.
