For a bunch of 13 year old kids, I would do a bottled BBQ sauce or that old fave...small bottle of catsup, small jar of grape jelly and half a jar of mustard.

funny you should ask that question, gail. i have made a meatloaf recipe that daisy posted and the first time i made it, my immediate thought was that it would make great meatballs and i'd put them into a crockpot with the sauce for an office pot luck dish. i haven't done it yet but i'm sure it would work really well! (NOTE: the first time i made it i didn't have any instant coffee and the sauce was very good. i just made it again the other night and the next time i think i'll increase the coffee a little bit more.)

Sauce:
1 onion, chopped very fine (optional)
1/4 cup water
1/2 cup tomato sauce
1/4 cup dry red wine or beef stock
1/4 cup Worcestershire sauce
2 tablespoons vinegar
1 teaspoon instant coffee
1/4 cup brown sugar
30g butter
2 teaspoons lemon juice
Saute onions until golden and add all other ingredients. Bring slowly to the boil, lower heat and simmer about 5 minutes. After loaf has cooked for 30 minutes, pour the sauce over the meat, return to oven and bake 45 minutes more, basting often. The sauce goes well with ribs or chicken.
