Spray a 9x13 baking dish with non-stick cooking spray, then set aside. Preheat your oven to 350°F.
Cook pasta in 4 quarts of lightly salted water. Cook the pasta according to the package directions.
While the pasta is cooking, mix together salsa, light sour cream, garlic powder, ground cumin, and onion powder in a medium sized bowl.
When pasta is done, drain, and pour it into a large mixing bowl. Add the sauce; stir to combine. Add drained corn, black beans, cooked chicken (shredded or cubed), and ONE CUP of the grated cheddar cheese. Reserve remaining cup of grated cheddar cheese to use later. Gently stir, until all ingredients are coated with sauce and are thoroughly combined. Pour into the baking dish, spreading to cover. Sprinkle remaining cup of grated cheddar cheese across the top of the casserole. Cover dish with aluminum foil, and bake in a preheated 350°F oven for 25 minutes. About 10 minutes before the cooking time is done, remove the foil and finish cooking.
Remove finished casserole from oven. Garnish with sliced green onions (or chives), and chopped tomatoes. If desired, you can also add avocado slices. Serve and enjoy!
Caloric calculation was calculated based on using light sour cream. Regular sour cream will work perfectly, but will increase calorie count for each portion.
