Southwest Steak Quesadillas are a delicious and satisfying Mexican-inspired dish. Tender strips of marinated steak are combined with sautéed bell peppers and onions, then layered with melted cheese between two tortillas. The quesadillas are cooked until golden and crispy, creating a perfect blend of flavors and textures. Serve these quesadillas with salsa, guacamole, and sour cream for a complete meal or appetizer.
