Creating Crispy Oven Baked Quesadillas is a straightforward process. Follow these easy steps for a delicious outcome:

1. Preheat Oven: Preheat your oven to 425°F (220°C). Line a baking sheet with parchment paper or a silicone mat.
2. Sauté Vegetables: In a skillet over medium heat, add olive oil. Toss in the chopped onion and bell pepper, cooking until tender (about 3-4 minutes).
3. Mix Filling: In a bowl, combine the cooked chicken (or beans), sautéed vegetables, and taco seasoning until well blended.
4. Assemble Quesadillas: Place one tortilla on the prepared baking sheet. Sprinkle half the cheese over half of the tortilla. Add a portion of the filling, then sprinkle the remaining cheese on top. Fold the tortilla over to cover the filling.
5. Repeat: Repeat the assembly process for the remaining tortillas. Ensure they are well spread out on the baking sheet so they cook evenly.
6. Bake: Place the baking sheet in the preheated oven. Bake for about 10-15 minutes or until the tortillas are golden brown and crispy.
7. Slice: Remove from the oven and let cool slightly. Use a sharp knife or pizza cutter to slice each quesadilla into wedges.
8. Serve: Arrange the wedges on a serving platter with salsa or guacamole on the side.

These simple steps will guide you in creating crispy, delicious quesadillas that everyone will love!
