Heart Healthy Minestrone Soup Recipe
Heat the oil in a heavy large pot over medium heat. Add the onion, carrots, celery and garlic. Sauté until the onion is softened, about 5 minutes. Add the tomato paste and bay leaf and stir. Add the Swiss chard and potato and sauté for 2 minutes. Add the diced tomatoes. Simmer for about 10 to 15 minutes.
Add the vegetable broth. Simmer until the potato pieces are tender, stirring occasionally, about 15 minutes. Stir in the beans, salt, parsley, oregano, thyme and red wine vinegar. Simmer until the beans are heated through and the soup is thick. Remove the bay leaf. Season with black pepper to taste.
