Get one of these "veggie trays" for your BBQ.
Cut up a mix of a few peppers (green, red, orange, yellow), red onion, garlic, mushrooms, green beans or whatever you like but the peppers turn out the best. Toss in olive oil. Heat the tray on the BBQ and pour the veggies and oil in. Cook, stir occasionally. Get some grill marks on the veg for the best taste.
Makes cooked veggies (mainly, peppers) taste amazing.
