Have you had Frito Pie? Do you like it? I don't really care for it, so it's an occasional thing.
Have you had a 3-way? A 4-way? 3-way = spaghetti, chili, and cheese. 4-way = spaghetti, chili, cheese, onions.
What do you think of Skyline Chili?
I think it's something you had to grow up eating, because it seems like spaghetti sauce to me. And it tastes...cinnamony, sort of.
