A Southwestern spin on Chili Mac, and tastier, I think. The kids LOVE it! It is so hard to find something all 3 of them like, so I HAD to post it! This recipe makes enough for plenty of leftovers. I use 3 boxes of Macaroni and Cheese, for time's sake, and taco meat seasoning that comes in the packet. If you don't use the boxed mac n' cheese, you will need to double the amount of shredded cheese.
