Rachel Ray's Veg-Head Three Bean Chili which I'll be making tonight. It was a hit in the past so hopefully they still like it tonight.
Also - Check the International isle in your local grocery store and look for falafel mix. There's one in my store (have to check the brand) that all you do is add water, make it into patties or balls, and fry it (use Olive Oil to be healthier, it's also cheaper in the international isle). We make it into patties and serve it on pita with avocado spread (just mashed avacados and lime juice).
