Ingredients

  • 2 potatoes, chopped
  • 2 tablespoons olive oil
  • 1 onion, chopped
  • 4 carrots, chopped
  • 2 stalks celery, chopped
  • 4 garlic cloves, minced
  • 1 teaspoon dried oregano
  • 2 teaspoons dried basil
  • 1/2 teaspoon ground black pepper
  • 3 3/4 cups water
  • 3 3/4 cups vegetable broth (or 35 broth cubes from freezing in ice cube trays)
  • 16 ounces stewed tomatoes, chopped
  • 1/2 cup tomato juice (from the can of stewed tomatoes)
  • 2 bay leaves
  • 2 cups dried red lentils
  • 1/2 lb fresh spinach, chopped (or 5 oz frozen spinach)
  • 2 tablespoons balsamic vinegar

Method

  • Cook the potatoes a little over half way before chopping. (I microwave them on high for about 5 minutes.).
  • In a large soup pot, heat oil over medium heat. Add onions, carrots and celery. Saute until onion is tender. Stir in potatoes, garlic, oregano, basil, and pepper. Cook for 1-2 more minutes.
  • Stir in water, broth, tomatoes, tomato juice, and bay leaves. (The liquid added should total 8 cups.) Bring to a boil. Add lentils and return to a boil. Reduce heat and simmer uncovered for at least 1 hour.
  • Cook frozen spinach separately, by the package directions, or skip this step if using fresh spinach. Add the spinach and vinegar to the soup in the last 5 minutes of simmering.
