So, pretend with me for a moment that your favorite mac and cheese recipe and your favorite taco recipe had a baby made out of creamy cheddar cheese and macaroni goodness mixed with spicy ground beef and topped with crumbled up crunchy tortilla chips. Got that in your mind? Welcome to my chili macaroni and cheese, which is all of that deliciousness baked up in your favorite casserole dish and just in time for those chili winter nights when the ravenous kids are around. Let's make it!
