Unstuffed Cabbage Soup

Sautée an onion, shredded cabbage, and a pound of ground meat or turkey (if using) in a pot. Once the mixture is fragrant and caramelized, add the tomatoes. Fill the can from the tomatoes with water and add it to the pot. Stir in brown sugar, a squeeze of tomato paste, and optionally 1/2 cup of tomato sauce and some lemon juice to help maintain color. Season with about 1/4 teaspoon each of salt and pepper. Add any other desired seasonings. Simmer until heated through and cabbage is tender. Optionally, stir in spinach or beans before serving.
