Rinse the red lentils under cold water.
Dice the carrot and onion, mince the garlic and ginger, and chop the parsley.
In a large pot, heat the olive oil over medium heat. Add the onion and sauté for 3-5 minutes until soft and translucent.
Stir in the ginger and garlic and sauté for 20 seconds.
Incorporate the carrot and tomato paste and sauté for 2 more minutes.
Add the lentils, vegetable broth, salt, cumin, chili powder, and black pepper and stir well.
Bring to a boil, then lower the heat and cover the pot.
Simmer for 20-25 minutes or until the lentils are tender and fully cooked.
Blend a portion of the soup and add it back into the pot.
Stir in lemon juice and chopped parsley. The red lentil soup is now ready to enjoy with a side of crusty bread.
