What else could I do to make my club more functional?

What appetizers and goodies should I make for my book club tomorrow?

• It's a women's book club in the evening. The hostess is providing the drinks and the house, I'm just providing the food. I have about 4 hours total to make and/or chill food after going to the store to buy ingredients. I want some awesome tasting stuff that's fun to eat, but not something that's super time consuming to make. Some of the ladies are on diets and eat only healthy food, most will eat nearly anything, so I need a variety.

• Answer:

  Do tapas style: marinated olives, garlic shrimp, ceviche, stuffed mushrooms, cheese& veggie plate, tuna stuffed tomatoes for the dieters. Yummy & easy.
