# 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, adjust to taste
06 - 1 teaspoon fresh lime juice
→ Butter
07 - 2 tablespoons unsalted butter, softened
# How to Make It:
01 - Combine mayonnaise, sriracha sauce, and lime juice in a small bowl until smooth. Adjust heat level as desired.
02 - Spread a thin layer of softened butter on one side of each bread slice; these will form the outer sides of the sandwiches.
03 - Place cheddar and Monterey Jack cheese evenly on the unbuttered side of two bread slices. Top with remaining slices, buttered side facing out, creating two sandwiches.
04 - Generously spread sriracha mayo over the buttered exterior of each sandwich.
05 - Warm a nonstick skillet or griddle over medium-low heat.
06 - Place sandwiches mayo-side down on skillet. While the first side cooks, spread sriracha mayo on the exposed top side.
07 - Grill each side for 3 to 4 minutes, pressing gently with a spatula, until the bread achieves a golden brown crust and cheese is melted.
08 - Remove sandwiches from skillet, allow to cool slightly for 1 minute, slice, and serve immediately.
