I "catered" my entire class reunion of 50 people for cheap! Does anyone in the family have those table top ovens (like crock pots, only you decide the temp) Get a bunch of those...
in one...quartered redskin potatoes, with butter, dill, fresh garlic and salt. stir it as it's cooking, should be ready in about an hour to hour and 1/2 cooked on 350 or 400.
in another...combine cooked pasta, spaghetti sauce and ground beef cooked with garlic onions and the spices you like, keep that on cooler...like 200 or just in a crock pot.
a third...frozen meatballs, mixed with equal parts cream of mushroom soup and sour cream, seasoned with parsley onion powder, pepper and garlic salt. (have some buttered egg noodles or rice to go with it...)
a salad, rolls, and a quick veggie (even something as simple as canned corn or peas)
based on how many people you have, you can save a ton on the ingredients at places like Gordon Food Service. the giant can of cream of mushroom soup there costs about the same as 2 little cans at the grocery store.
it's easy!!!
