Don't forget "hot dish," which is a blanket term for any combination of gooey and non-gooey ingredients thrown together in a casserole dish and baked for 45 minutes at 350 degrees. Popular ingredients include chow mein noodles, hamburger, cream of mushroom soup, taco sauce, canned tuna, potato chips, pats of margarine, tomatoes, American cheese. Not necessarily all at once.

You bring hot dish (note: no article) to the potluck.
