Preheat the oven to 350F and spray a 9x13 casserole dish with some non stick spray.
Cut the 10 small biscuits into 6 pieces each.
Use just 1/4 cup of your enchilada sauce and spread it in the bottom of casserole dish - just enough to cover it.
Place 1/2 of the cut biscuits in the dish on the sauce.
In a bowl, mix the chicken with the remaining 3/4 cup of enchilada sauce, diced peppers, diced tomato and chili powder.
Spoon half of the chicken mixture on top of the biscuits, spreading it out evenly.
Sprinkle 1/2 cup of cheese, then repeat the layers with the remaining biscuits, chicken mixture, and cheese.
Top with diced green onion then loosely cover with foil and bake for 35 minutes. After 35 minutes, remove foil and bake for another 15 minutes.
Top with fresh sliced avocado and fresh chopped cilantro (optional).
Cut into 6 equal servings, each one weighing approx 6.5 oz.
