Ingredients

For the Soup Base

  • 2 tablespoons olive oil
  • 1 medium onion, diced
  • 1 medium carrot, diced
  • 2–3 stalks celery, diced
  • 2 cloves garlic, minced
  • 1 teaspoon cumin
  • 1 teaspoon paprika
  • ½ teaspoon salt
  • 1 tablespoon tomato paste
  • 2 cans (14 oz) crushed tomatoes
  • 1 ½ cups green lentils high in protein
  • 4 cups vegetable stock or mushroom broth for deeper umami

For the Finishing Touch

  • 2 cups shredded kale can substitute with spinach for a lighter version
  • 2 tablespoons flax seeds or chia seeds for thickness
  • Salt and pepper to taste

Instructions

Preparation

  • Heat olive oil in a large pot, add onion, carrot, and celery, and let them soften slowly.
  • Add garlic, cumin, paprika, and salt, stirring until the spices release their fragrance.

Cooking

  • Add tomato paste, crushed tomatoes, green lentils, and vegetable broth. Bring to a boil, then reduce heat and let it simmer for about 30–35 minutes until the lentils are tender.
  • Stir in kale until wilted, then sprinkle flax seeds for added protein and omega-3 boost.
  • Season with salt and pepper to taste.

Serving

  • Serve hot, topped with a drizzle of olive oil or a sprinkle of extra flax seed.
