Step 1: Preheat Your Oven. Start by preheating your oven to 400°F (200°C) for even baking.
Step 2: Sauté the Vegetables. Heat olive oil in a skillet, add onion and bell pepper, sauté for 5-7 minutes until tender.
Step 3: Mix the Filling. Combine sautéed vegetables with chicken and spices in a mixing bowl, stirring well.
Step 4: Assemble the Quesadillas. Lay 4 tortillas on the sheet pan, spread half the mixture, top with cheese and another tortilla.
Step 5: Bake. Bake in the oven for 15-20 minutes until tortillas are golden brown and cheese is melted.
Step 6: Slice and Serve. Allow to cool, slice into wedges, and serve with toppings.
