In a large saucepan or Dutch oven, heat the toasted sesame oil over low heat.
Add the cumin seeds and toast for 1 minute until fragrant. Increase the heat to medium-high, stir in the carrot, celery, and leek, and sauté for 3 minutes until slightly softened. 2.
Pour in the vegetable broth and rinsed lentils.
Bring the mixture to a simmer, then reduce the heat to low, cover, and cook for 20 minutes, or until the lentils are tender. 3.
Stir in the minced garlic and cook for 5 more minutes to allow the flavors to meld.
Season with salt and pepper, if desired. 4. Ladle the lentil soup into four bowls.
Garnish each with a generous sprinkle of chopped smoked almonds and a cool dollop of plain Greek yogurt.
Add ¼ teaspoon of smoked paprika along with the cumin seeds for an even deeper, smokier flavor. A squeeze of fresh lemon juice just before serving will also brighten everything up.
