Bring a large oven safe pot (like a dutch oven**) of water to a boil. Salt generously and cook pasta for half the time recommended on the box. Drain and set aside.
In the same hot pot, melt butter and saute onions, garlic, peppers, jalapenos and corn until tender...about 7 minutes or so.
Sprinkle in flour and stir. Cook 2 minutes, then pour in chicken stock and whisk.
Stir in cumin, chili powder, salt and black pepper. Increase heat to thicken sauce.
Turn of heat and add mozzarella cheese, one cup of the cheddar cheese, heavy cream, chicken and cooked pasta. Stir to combine.
Top with crushed tortilla chips and the remaining 1/2 cup of cheddar cheese. Bake uncovered or 20-30 minutes or until hot and bubbly. Serve.

Notes
*Reduce or omit jalapenos if sensitive to spicy foods. **I wanted this to be a one-pot recipe, but if you don't have a dutch oven or other oven safe pot, feel free to transfer the pasta to a casserole dish and bake.
