Cheese and crackers (a nice variety of cheeses, some soft, semi-soft, harder, etc., perhaps a salami) with fruits
Fresh veggies and dip (carrots, broccoli, tomatoes, peppers, zucchini, summer squash, celery)
Spinach and artichoke dip with pita chips
Some kind of meat, such as Swedish or sweet'n'sour meatballs, chicken wings
Crostini with a spread
Mini quiches
Stuffed mushrooms
All of those are exciting and delicious to me!
