Prep the oven: Preheat the oven to 425°F. Spray an 18×13-inch sheet pan with cooking spray.
Make the chicken filling: In a large skillet heat the olive oil. Add the onion, bell pepper to the
skillet and cook for 3 minutes until the onion begins to soften and gets translucent. Add the
chicken, chili powder, cumin, smoked paprika, garlic powder, salt and pepper to the skillet, stir
well and cook for 5 to 7 minutes until the chicken is cooked through. Stir in the black beans and
corn kernels and cook for an additional 2 minutes until the beans heat through.
Layer the bottom tortillas: Place 6 of the flour tortillas around the edges of the sheet pan, with
the tortillas hanging halfway over the edge of the pan, leaving a gap in the center. Place 1 tortilla
in the bottom center gap.
Add the filling: Evenly spread the meat mixture over the tortillas. Sprinkle with the two cheeses
evenly over the meat mixture.
Finish assembling the quesadilla: Place the last tortilla in the center of the mixture. Carefully
begin folding the tortillas that are hanging over the edge of the pan, towards the middle. Place a
second sheet pan on top of the folded tortillas and press down a bit.
Bake: Transfer the baking sheets to the oven and bake for 20 minutes. Remove the top sheet pan
and bake for an additional 5 minutes until the top is golden brown.
Serve: Remove the sheet pan from the oven and allow the quesadilla to slightly cool before
cutting it into servings. Serve with sour cream, salsa, pico de gallo, or guacamole if desired.
