To turn Summer Garden Soup into a main dish for lunch or a light supper, stir in small pieces of ham or cooked chicken, turkey or lamb just before serving.
The vegetables for Sweet Vegetable Soup can be cooked alongside a meat main dish. Meat needs a longer oven time, so the soup can be prepared while the meat finishes. Leave the meat to rest on top of the oven while you serve the soup.
