I am throwing a bday party this weekend for my roommate and I need some hors d'oeuvre ideas. I haven't got a big budget and the crowd will be mostly omni (including the birthday boy), with a few vegans and vegetarians. I want to make sure there are plenty of veg options that our omni friends will eat too. The last thing i need are a ton of leftovers! I need recipes that are cheap, simple, and classiness is a definite plus. any ideas?
