Step 1

Combine 2 Tbsp. oil, the chili powder, cumin and salt; mix well. Brush over both sides of chicken, bell peppers and onion slices. Grill* chicken and vegetables over medium coals 5 minutes per side or until chicken is cooked through and vegetables are tender; transfer to chopping board. Cut chicken and peppers into bite-sized chunks; separate onion slices into rings.

Step 2

Brush remaining 1 Tbsp. oil over one side of each tortilla. Place 4 tortillas, oiled sides down, on cookie sheet. Combine chicken, vegetables and cheese; divide mixture over tortillas. Top with remaining tortillas, oiled sides up.

Step 3

Bake in a preheated 450°F oven for 6 minutes or until golden brown on bottom. Use a large spatula to turn quesadillas over. Continue baking until tops are golden brown, about 2 minutes. Cut into quarters.
