Bell peppers, onions, potatoes, cherry tomatoes, zucchini, mushrooms, eggplant, tofu, chunks of meat, etc. The key is to get everything cooked at the same time. To do this, parboil or microwave anything which would take longer to cook until just tender, eg. potatoes, carrots, corn on the cob (1" slices). Marinate everything in your favorite mix and continue to baste as it cooks. Typical marinade: 1/2 c. oil, 1/4 c. lemon juice, 1 tbs. honey, minced garlic, salt, pepper, finely chopped herbs. (one can blenderize these too) Thyme, oregano, basil, and rosemary can all be used. Vinegars can replace the lemon juice.
