So we're having a cookout in a couple weeks, and as it turns out more people than we expected have RSVP'ed yes. This is wonderful, but we're trying to stay on a reasonable budget. I don't want to have a potluck because I'm an annoying control freak and want to control the menu. Anyone willing to share their favorite cheap cookout-friendly recipes? I'm a skilled cook so it doesn't need to be easy, just not extravagant. Ways to stretch meat as well as things that would be good for vegetarians are welcome, as well as apps, sides, and desserts. Any secret recipes?
