Optionally, skewer shrimp with vegetables, or separately.
If using a George Foreman grill, lay shrimp on hot grill in a single layer, close lid. They're done in about a minute or two. If using an outside grill, rub grill with vegetable oil then lay skewered shrimp and vegetables in a single layer on grill. Turn after about 2 minutes. Cook only until shrimp turn pink. Don't overcook. If you like veggies done more than crisp, put those on first.
