Shred the chicken. See notes below* on how to poach the chicken.
Preheat oven to 400 F.
Heat vegetable oil (2 tablespoons) in a large oven-safe pan over medium heat.
Once shimmering, add chopped onion (1 cup) and chopped bell pepper (1). Saute until soft, about 10 minutes.
Turn off the heat in the pan, and stir in salt (1 teaspoon), pepper (1/2 teaspoon), diced green chilis (4 Ounces), taco seasoning (4 tablespoons), and water (1/4 cup). Stir until the taco seasoning dissolves.
Add shredded chicken (3 cups), cottage cheese (1 cup), red enchilada sauce (12 Ounces), and cheddar (1 cup). Stir until well combined and the chicken is coated in sauce.
Sprinkle remaining cheddar (2 cups) on top.
Bake in the preheated oven for 15 minutes, or until heated through and the cheese starts to brown around the edges.
Serve over cauliflower rice and top with your favorites. Enjoy!
