Chili mac is something I'm sorry to say I didn't invent. It’s such a simple concept, combining 2 great snacks to make an even better one! It’s like the Chili Billy (Chili on Nachos). You can mix and match whatever kind of chili and macaroni & cheese, but it's easiest just to pick up microwave versions of each. Not the healthiest, but easy to make, doesn’t require fancy kitchen tools or an oven, it’s cheap, and the ingredients won’t go bad.
