# Ingredient list:
→ 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)
→ Sriracha Mayo
04 - 3 tbsp mayonnaise
05 - 1 to 1½ tbsp sriracha sauce, adjusted to taste
06 - 1 tsp fresh lime juice
→ Butter
07 - 2 tbsp unsalted butter, softened
# Step-by-step guide:
01 - Combine mayonnaise, sriracha sauce, and lime juice in a small bowl until smooth. Adjust sriracha for desired heat.
02 - Spread a thin layer of softened butter on one side of each bread slice; these will be the exterior of the sandwiches.
03 - Arrange cheddar and optional Monterey Jack cheese evenly on the unbuttered side of two bread slices. Top with the remaining slices, buttered side out, to form two sandwiches.
04 - Spread a generous layer of sriracha mayo on the outside (buttered side) of each sandwich.
05 - Preheat a nonstick skillet or griddle over medium-low heat.
06 - Place sandwiches mayo side down on the skillet. While the first side cooks, spread sriracha mayo on the top side.
07 - Grill each side for 3 to 4 minutes, pressing gently with a spatula, until bread is golden brown and cheese is melted.
08 - Remove sandwiches from heat, let rest for 1 minute, then slice and serve warm.
