Heat a large sautée pan over medium-high heat; add avocado oil.
Sauté chopped onion and bell peppers until translucent, about 5 to 10 minutes. Add taco seasoning, water, shredded chicken breast, and 1/2 can enchilada sauce; mix to combine. Remove from heat.
In a medium bowl, combine cottage cheese, shredded cheeses, and sour cream; mix to combine. Set aside.
Coat the bottom of a 9 x 13-inch baking pan with enchilada sauce. Layer with 4 corn tortillas, breaking them into halves or quarters to cover the bottom of the baking dish.
Spoon 1/2 of the chicken and vegetable mixture on top of the tortillas, pressing into an even layer. Cover the chicken mixture with 1/2 of the cheese mixture and continue layering as follows: 4 corn tortillas, remaining chicken mixture, enchilada sauce, 4 corn tortillas, enchilada sauce, and remaining cheese mixture.
Sprinkle with extra shredded cheese, if desired, and bake uncovered for 45 minutes until cheese is lightly browned and bubbly.
(Optional) Top with cilantro, sour cream, fresh jalapeño, salsa, or avocado.
