  • 1 tablespoon oil
  • 1 medium onion diced
  • 2 cloves of garlic minced
  • 1- inch ginger peeled and minced
  • 2 tomatoes finely diced
  • 1 small chili Use two if you like it spicy, finely sliced
  • 1 cup red lentils
  • 2 and ½ cup water
  • ¼ cup soy sauce
  • 3 tablespoon maple syrup
  • 2 tablespoon tamarind paste
  • ¼ cup water
  • 2 tablespoon lime juice


  • Heat the oil in a large saucepan over medium heat. Once hot, add the onion, garlic, and ginger, and sautée for about 5 minutes, or until the onions are golden brown.
  • Add the diced tomatoes and cook for another 5-8 minutes, or until tomatoes are soft and saucy. Add the sliced chili and stir to combine.
  • Next, add the red lentils, water, soy sauce, and maple syrup. Bring to a boil, then reduce to a simmer and cook uncovered for 25-30 minutes. The lentils must be tender.
  • In the meantime, prepare the tamarind juice. In a small bowl, stir together the tamarind paste with the warm water. Let it sit for at least 10 minutes before straining to keep only the juice.
  • Once the lentils are cooked, stir in the tamarind juice and lime juice.
  • Serve with a dollop of vegan yogurt or coconut milk, and chopped cilantro! This lentil soup will keep for up to 3 days in the refrigerator.
