In a large no-stick frying pan over medium heat, saute onions, mushrooms, peppers, and garlic in 1 tbs. water until softened, about 5 minutes. Add eggplant and 2 tbsp. water; saute until softened, about 10 minutes. Add the tomatoes (with their juice), 1 1/2 cups water, barley, chili sauce, parsley, honey (or syrup), Worcestershire sauce, marjoram, and black pepper. Bring to a boil and simmer for 20 minutes, or until barley is tender.
