Equipment

Ingredients

  • 4 cups vegetable broth or stock divided
  • 1 small onion chopped
  • 2 cloves garlic minced
  • 3 carrots chopped
  • 3 stalks celery chopped
  • 1 tablespoon Italian Seasoning
  • 1 teaspoon cumin
  • salt and pepper to taste
  • 1 15 oz can of diced tomatoes
  • 1 cup red lentils rinsed
  • 1 bag of fresh spinach 16 oz

Instructions

  • In a large pot pour ¼ cup of the vegetable stock on the bottom of the pan. Add onions and garlic. Cook on medium heat until translucent.
  • Add carrots and celery. Cook for an additional 5 minutes.
  • Add Italian seasoning and cumin, and salt and pepper to taste. Stir to coat vegetables.
  • Add the remainder of the vegetable stock, can of diced tomatoes and lentils. 
  • Bring to a boil then cover and reduce to medium low heat. Cook for 30 minutes stirring occasionally. 
  • When you're ready to serve add the bag of spinach and stir to combine. It will look like a lot of spinach to add, so add one handful at a time until it is absorbed and combined with the soup. Spinach wilts down quickly. Serve topped with fresh lemon and fresh chopped parsley (optional).
