My family loves mac & cheese and I try to come up with different ways to make it so it doesn't become the "same old same old" sort of thing. This one was inspired by the Nacho Dip I had made at Christmas.
Cook your pasta according to the directions on the package. While the pasta is cooking cut your cheese up into 1/2 inch cubes.
After the pasta is cooked, drain and return to the pot. On medium heat add the cubed cheese and the can of rotel diced tomatoes. Do not drain. Stir occassionaly until the cheese is melted and nice and creamy.
Pour the noodle and cheese mixture into a oven proof dish, sprinkle crushed tortilla shells on top and bake in a preheated oven at 350° for 20-25 minutes. The cheese will be nice and bubbly and the top will be slightly browned. Serve hot.
