We used to have a guy that sold Hot Dogs off the back of his truck, they were pre-cooked so he had a small camping grill to keep them warm. He had a cooler filled with drinks too. It's as simple as you can get.What are some simple foods that could be provided at a launch with relatively little effort? Burgers take too long, too much work, too much grill space. A portable gas grill would provide some options: chili dogs, pulled pork BBQ, nachos. If you have a generator...good quality coffee (real half-and-half please, not the powdered plastic stuff; charge appropriately) and muffins or donuts for mornings. Other ideas?
