We've made it a family tradition to have appetizers for dinner when we open Christmas gifts. One standard is an artichoke dip that came from my aunt Ann. We usually have this with chips, but I like the leftovers as a sandwich spread too. It's so easy to whip together and bakes in only twenty minutes. It's got just the right zing (though I always add extra cheese, but that goes without saying). It's easy to customize too: if you don't like mushrooms, leave that out and throw in some olives, or whatever your preference.
What are your favorite appetizers? I'd love to see some recipes in the comments thread!
