In a large, nonstick skillet over medium heat, saute onion, green pepper and red pepper in oil until tender. Add garlic and saute an additional minute. Stir in chicken, soups, tomatoes and chili powder.
Line a 9 x 13 inch baking pan with half of the tortilla strips.
Top with half of the chicken mixture and 1 cup of cheese. Repeat layers.
Bake uncovered for 30 minutes or until cheese is completely melted.
Notes
Other types of condensed soups (we know a lot of people don’t always have cream of celery on hand, so you could definitely do 2 cans of cream of chicken, or substitute another type of condensed soup. It may change the flavor slightly, but not too much!)
