Bridal shower food ideas?

It is a shower for my best friend, and her list is about 50 people to be invited to it. I am footing the bill myself, so I need ideas for easy to make (but yet cheap!) food ideas. There isn't a theme, but I wanted a variety of food- butnot all sweets since we have the cake. It is in the afternoon, so I don't need a meal, just appetizer-type stuff. Any ideas (and recipes or links!) would be sooo helpful!! Thanks!
