My son is graduating from High School in a couple weeks, and I'm going to be feeding about 20 people after the ceremony. I'm looking for ways to step up a traditional outdoor BBQ. So far, I'm thinking tri-tip and chicken, maybe chili beans or baked beans, baked potatoes, garlic bread, a salad of some kind and fruit. It's all great food for a BBQ, but I'd like to add a little WOW to it for my guests. Any ideas?
