Prepare pasta per package directions. Drain and return to pot.
Dice cooked chicken breasts into 1" pieces. Add to pasta pot.
Combine enchilada sauce, corn, black beans, 1 cup cheese, cream cheese, and seasonings with pasta. Cook over medium-low heat until cream cheese blends smoothly with pasta.
Serve with additional shredded cheese on top, jalapenos or whatever toppings are desired.
Notes
If sauce is too thick after adding all ingredients, add milk 1/8 cup at a time until desired consistency is created.
