I put out cheese (a variety-brie, manchega, cheddar, etc) and crackers/sliced french bread, nuts (spiced pecans, pistachio, cashews).
The meatball thing was already mentioned. Sometimes I just heat those in a pan too.
We've made roll-up with tortillas...THIN layer of... ham (regular or Italian), spreadable cream cheese (sometimes I mix in herbs or spices for a kick), a layer of baby spinach leaves. Then I roll it as tight as I can. wrap and let sit for an hour or so in the frig. Then I take it out and cut into slices, sometime on a diagonal. I also make them with only cheese for my kosher friends.
On a small skewer put a cherry tomato and basil leaf.
In those mini cupcake pans I make mini quiche.You can use ready made crust (not cooked and in a roll) get by eggs and cheese in most stores. I cut circles out with a soup can (emptied some time ago), and push them into the holes in the pan. Mix 9 eggs, 1/2 milk, cheese (as much as you like. We like a lot...1 to 2 cups), season with salt/pepper and anything else that you like...sage, terragon, rosemary, etc.)pour into cups- about 3/4 full. Bake on 375 until done. They are tasty.
I was just at a party that served, roasted lamb ribs. They were a bite or two, I hear.
