I'm hoping the experts out here will help a relatively new (but very enthusiastic) home cook. We're having a house party, and I'd love to make some delicious appetizers for around 30 people at a cocktail party. Of course, I don't have a lot of money to spend, and don't want to spend the whole party in the kitchen! Any suggestions for delicious, easy dishes that will help keep a crowd munching and drinking happily? Thanks!
