I'd like to give my friend and her fiancé an engagement party. Im looking at maybe 15 to 20 people, plus her two voracious-eater teens. I don't necessarily want to do a full dinner, am thinking more of finger foods and appetizers plus somevdrinks and desserts. The caveat? Everything must be kosher and vegetarian. And if some things are do ahead, even better! So please, swamp me with your favorite appetizer, dips and finger food recipes! Extra credit if said recipes are easy!
