Cheddar goes with chili and the sweet pickled jalapenos go even better. The sweet/hot pairs well with the savory. Minced onions and crushed Doritos round out the garnishes.
Chili dogs same way except plate replaces the bowl.
It seems off a bit to call it chili mac but chili spaghetti is not really any better sounding. I forgot the crushed chips or they would have been there.
