1 can (14-1/2 ounces) no-salt-added diced tomatoes
1 can (6 ounces) tomato paste
1 tablespoon lemon juice
2 cups cooked brown rice
In a Dutch oven, saute onion in oil until tender. Add garlic; cook 1 minute longer. Add the water, broth, lentils, carrot, green pepper, oregano, basil and, if desired, pepper flakes. Bring to a boil. Reduce heat; cover and simmer for 20-25 minutes or until lentils are almost tender.
Stir in the tomatoes, tomato paste and lemon juice. Bring to a boil. Reduce heat; cover and simmer 10 minutes longer or until lentils are tender. Serve with rice. Freeze option: Freeze cooled soup in freezer containers. To use, partially thaw in refrigerator overnight. Heat through in a saucepan, stirring occasionally and adding a little broth or water if necessary. Serve with rice.
