Preheat oven to 350F
Add olive oil and mushrooms to a large covered skillet over high heat, cover and let steam for 2 minutes
Add onions, garlic, red pepper flakes, and Adobo seasoning sauté until onions are translucent
In a large microwave-safe bowl, combine one can of enchilada sauce with
the can of refried beans, heat until easy to mix, stir to combine (this
thickens the finished sauce)
Add the beans, corns, one can of enchilada sauce and chilies to the
mushrooms and onions, bring to a boil, then reduce heat to low, add the
bell pepper and zucchini and simmer for 10 minutes
Add the refried bean mixture to the sauce, stir to combine and remove from the heat
Spray a large 9×13 inch casserole with oil, lay 4 ½ tortillas to cover the bottom completely
Cover the tortillas with ½ the shredded chicken
Cover the chicken with ½ of the sauce
Cover the sauce with ½ of the cheese
Repeat, lay 4 ½ tortillas to cover the first layer
Cover the tortillas with the remaining shredded chicken
Cover the chicken with the remaining sauce
Cover the sauce with the remaining cheese, pickled jalapenos and sliced red onions
Bake @ 350F for approximately 30-40 minutes until the cheese is melted
and the casserole is bubbly, sprinkle with chopped fresh cilantro and
serve
