Step-by-Step Instructions

1. Cook the Steak
   Heat 1 tablespoon of vegetable oil in a large skillet over medium heat. Place the diced skirt steak in an even layer and season with 2 tablespoons taco seasoning. Sauté for 1–2 minutes per side until slightly browned.
2. Add Vegetables
   Add the diced red bell pepper and yellow onion to the skillet. Sauté with the steak for 5–7 minutes, until the steak is cooked through and the vegetables are tender.
3. Add Salsa
   Pour ¼ cup salsa over the steak and vegetable mixture. Toss to coat evenly and sauté for a few minutes to blend the flavors. Remove from heat.
4. Heat Tortillas
   Heat a griddle or cast-iron skillet over medium-high heat. Place a flour tortilla on the skillet.
5. Assemble Quesadillas
   Sprinkle a small amount of each cheese on one half of the tortilla. Layer with the steak and vegetable mixture, then add more cheese on top. Fold the tortilla in half to create a half-moon shape.
6. Cook Quesadillas
   Cook until the bottom side is golden brown, 1–2 minutes. Flip and cook the other side until golden brown as well. Watch closely as they brown quickly.
7. Serve
   Remove quesadillas onto a cutting board. Slice into wedges and serve immediately.
