Preheat oven to 350 degrees F.
Cook and cube chicken.
(This is actually 8 pounds of chicken (for this recipe and another I'm doing this week.))In frying pan, sauté chopped green chile with onion and garlic. Add corn, olives, and tomatoes. Remove from heat and dump into a big bowl with the chicken.
Rinse black beans, add to the bowl.
In a large pot of boiling, salted water cook the pasta to al dente. Drain and add to the chicken and vegetables and mix well.
In a large pot, melt the butter. Whisk in the flour, paprika, and mustard, keep it moving for about five minutes. Make sure it's free of lumps. Stir in the milk, and enchilada sauce. Simmer ten minutes.
Temper in the egg. Stir in 3/4 of the cheese. Pour into the mix and pour into a 2 quart casserole dish. Top with remaining cheese and crushed chips. Repeat into a second dish.
Bake for 30 minutes. Remove from oven and rest for five minutes before serving.
You can garnish with sour cream if you'd like.
