Step 1

Preheat oven to 350 F. Grease a casserole dish with 1 tablespoon of olive oil.

Step 2

In a large skillet over medium heat, add the remaining olive oil, and sautée the onion and bell pepper for around 5 minutes.

Step 3

In a large bowl, stir together the chicken, chicken soup, mushroom soup, tomatoes, cayenne pepper, and cooked vegetables.

Step 4

Next, arrange half of the tortillas in an even layer at the bottom of the casserole dish. It's fine if they overlap.

Step 5

Spread half of the chicken mixture over the tortillas. Sprinkle with half of the cheese.

Step 6

Repeat the layers with remaining ingredients, finishing with cheese on top. Depending on how big your casserole dish is, you may have two layers or three layers.

Step 7

Bake, uncovered, for 30 minutes until the top is bubbling and crispy.
