If bronco people have coalesced around pineapple pizza, then surely Slate is a plain cheese pizza. It lets everyone customize it with the toppings they want, and you don't pay for anything you don't want.
slate food is a plain hamburger. Cheap, simple, american, and gets the job done. If you want you can accessorize it with cheese, pickles, lettuce and tomato. Can upgrade meat to wagyu. Can add another patty, and can add all kinds of fancy toppings like mushroom and swiss, bacon, avocado etc.
