Dolmades. I grew up eating these and they are great. The link below is to a recipe for cold ones that can be made the day before. There are also some recipes for hot ones madw with lamb but I have found they do not make a good dish to set out and pick at.

Gypsy's cheese tray is a great idea and places like Sam's & Costco sell cubed cheese that all you need to do is set on a tray. If you do not have a membership I have seen the cubed cheese in the dairy case at my local grocer (but costs a bit more)
Sams and Costco also sell little things in the freezer case like Artichoke and Spincah tarts.
Maybe some brie and crackers would be nice. Make one with raspberry jelly on it and the other just warmed.
Maybe some Spanakopita? (my Greek heritage is showing) Easy to make and awesome flavor!

Maybe grab some phyllo dough and make Baklava
Puff pastry and wrap some mini dogs in it and make a dipping sauce out of a bit of spicy mustard and honey (mix to your taste and nuke in the microwave to loosen up)
Mini Calzones can be made easily with the pizza dough from the same section that you buy the cans of buttermilk biscuits. Roll it out and cut little squares. Throw a bit of sauce and some cheese maybe some pepperoni or ham, whatever grabs you by the ass.
A vegetable tray is always good. Some mini carrots and such with a few dressings for dipping.
Just some ideas, hopefully one or two will help you out.
