One of my dreams is to one day own a mac and cheese food truck!
You can just about make any flavour and then toss it through macaroni and bake it. Imagine all the things you like, then mix it in with macaroni. For example, I love chili and chili con carne, mix it in with macaroni, put cheese on top and and bake it in the oven and you have chili mac and cheese. You can also have it cold like a salad like they do in the Philippines. There they have a salad with macaroni, its usually with pineapple, ham, palm seeds, cheddar cheese and coconut dressed with mayonnaise or sour cream, sounds weird but bloody tasty stuff.
