FIRST STEP: SAUTÉ THE VEGETABLES

1. Heat the Olive Oil: In a large pot, heat the olive oil over medium heat. Add the chopped onions and sauté for about 3-4 minutes, or until they become soft and translucent.
2. Add Garlic, Carrots, and Celery: Add the minced garlic, chopped carrots, and celery to the pot. Continue to sauté for another 5 minutes, stirring occasionally, until the vegetables begin to soften.
3. Add the Tomatoes: Add the diced tomatoes to the pot and stir. Let the mixture cook for another 2-3 minutes, allowing the tomatoes to release their juices and soften.

SECOND STEP: ADD THE SPICES AND BROTH

1. Stir in the Spices: Sprinkle in the ground cumin, turmeric, coriander, salt, and pepper. Stir well to coat the vegetables with the spices, allowing the flavors to meld together.
2. Add the Lentils and Broth: Pour in the dried lentils and vegetable broth. Stir everything to combine. Add the bay leaf for extra flavor.
3. Bring to a Boil: Turn the heat up and bring the mixture to a boil. Once boiling, reduce the heat to low, cover the pot, and let the soup simmer for 30-35 minutes, or until the lentils are tender.

THIRD STEP: FINISH THE SOUP WITH LEMON

1. Add Lemon Juice and Zest: Once the lentils are cooked, remove the bay leaf from the soup. Stir in the fresh lemon juice and lemon zest, adjusting the amount to suit your taste. This will add a bright, refreshing flavor to the soup.
2. Taste and Adjust: Taste the soup and adjust the seasoning as needed. You can add more salt, pepper, or lemon juice depending on your preference.

FOURTH STEP: SERVE AND GARNISH

1. Serve the Soup: Ladle the soup into bowls, ensuring each serving has a generous portion of lentils and vegetables.
2. Garnish: Top each bowl with a sprinkle of fresh cilantro or parsley for a burst of fresh flavor. You can also add a dollop of yogurt or tahini for creaminess.
3. Pair with Bread: Serve the soup with crusty bread or pita for a complete meal. The bread can be used to soak up the flavorful broth and complement the soup’s texture.
