  • 1 tablespoon minced fresh ginger

  • 1 tablespoon ground cumin

  • 1/4 teaspoons cayenne pepper, or more to taste

  • 1 (425g / 400g) can whole tomatoes, or 5 large fresh tomatoes chopped

How to make Four Corners Lentil Soup

  1. Heat the oil in a medium pot, add the onions, garlic, and ginger, and sauté for 5 minutes, until soft. Add a pinch of salt, the cumin, and the cayenne, and stir for another minute or so, until fragrant.

  2. Add the tomatoes, 3 slices of lemon, and the lentils. Then add the vegetable broth and stir well. Cover the pot and bring the mixture to a boil. Reduce the heat and simmer for about 30 minutes, until the lentils are soft. Add a squirt of maple syrup to balance the flavour, if desired.

  3. Serve hot, garnished with the coriander, spring onions, or parsley, and topped with a slice of lemon.
