Step 1

Heat the oil in a large heavy-bottomed soup pot or dutch oven over medium-high heat. Add the onion and celery and cook, stirring occasionally, until softened, about 8 minutes. Add the garlic, harissa, cumin, turmeric, cinnamon, and ginger. Continue to cook until fragrant and toasty, about 1 more minute.

Step 2

Mix in the crushed tomatoes, celery leaves, harissa, stock, and half of the cilantro, and bring to a gentle boil. Reduce to a simmer and continue to cook, uncovered, for 15 minutes.

Step 3

Add the lentils and chickpeas and season generously with salt. Cook for 30 more minutes, taste, and adjust harissa and seasonings as needed. Continue to cook until the lentils are soft. The soup should thicken, but if it gets too thick, add more stock or water as needed. Be sure to add extra salt along with the extra liquid.

Step 4

Mix in and top with the remaining cilantro, and serve warm with lemon wedges. Top with greek yogurt and toasted almonds, if desired.
