It sounds like she is making finger foods, so a casserole might not work. Stuffed or deviled eggs, marinated olives, sweet/spicy roasted walnuts, mini meatballs...are some ideas off the top of my head. There are some cheeseball recipes on the Recipe Exchange.

I agree; I'd stick with finger foods, sounds like she doesn't want to deal with plates and forks, etc.

I just added a few cheese ball recipes at Recipe Exchange, you might want to try there. Also, how about stuffed celery sticks, miniature cheese balls with a pretzel stuck in, marinated artichoke hearts, relish tray, pepperoni & cheese on toothpicks.....

If the hostess is one that really puts a spread on....pretty much on her own....how about a "morning after basket" for her. Speciality coffee, tea, a fresh breakfast bread, jam etc.

How about a crock pot of nacho cheese,some salsa and a couple bags of nachos.
You could also bring disposable plates ect.

cookie platters are always enjoyed, maybe an artichoke spinach dip with tortilla chips or a crock of chili (bring bowls and spoons).

Seeing as how it is a Halloween party, I would bring something in the "spirit" of the holiday! A kitty litter cake or witches fingers cookies are lots of fun. Dress up everyday things in halloween themes. If you are bringing a cheese ball. Make it into a spider by sticking black licorice whips into it for legs. Have fun with your food! NancyLouise
