2 cups coarsely crushed tortilla chips
1.5 lbs. skinless boneless chicken breasts
1 4 oz. can chopped green chilies
1 ½ cups frozen corn
2-3 tablespoons taco seasoning
1 (10.75 ounce) can condensed cheddar cheese soup (NOT diluted) I used Campbell's Healthy Request
1/2 cup milk I used nonfat, but any type will work
1 (14.5 ounce) can petite diced tomatoes, drained
1 cup shredded cheddar cheese
For topping: sliced green onions, sliced black olives, diced avocado, sour cream, salsa, additional crushed chips

Preheat oven to 400 degrees F. Spray a 13-by-9-inch casserole dish with cooking spray.
Place broken tortilla chips in the bottom of prepared dish. Top with chicken, green chilies, and frozen corn. Sprinkle with taco seasoning.
In a small bowl, whisk together condensed soup and milk to form a cheese sauce. Spread sauce evenly over top of casserole.
Cover with foil and bake for 30 minutes.
Remove foil, sprinkle with tomatoes and shredded cheese, and return to oven (uncovered) for approximately 10-20 more minutes (or until chicken is cooked through and cheese is melted). The total cooking time will vary, depending on the thickness of your meat.
Garnish with desired toppings and serve!

You can prep this casserole in advance and keep it covered in the fridge until you are ready to bake.
Make sure to grease your baking dish to make sure nothing sticks or burns underneath.
Feel free to add extra spices to the mix, such as red pepper flakes or cayenne pepper, for extra heat.
You can add your favorite toppings to this casserole, there are no limits.
If you're short on time and want to use pre-cooked chicken, you totally can! Shredded rotisserie chicken is a great option for this chicken taco bake.
Use a can of Rotel green chilies and tomatoes in the chicken taco mixture to add more flavor and a hint of spice to the casserole.
Cube up Velveeta cheese and mix it into the casserole dish, or in extra shredded cheese for a cheesy casserole filling.
Cooking just for two? Cut the ingredients in half and prepare the casserole in an 8-inch square baking dish. The cooking instructions remain the same.
