Step 1

Melt butter in a large pot, add the onions and saute until soft, 5 to 7 minutes. Stir in the garlic, spices, and salt and pepper, and saute another minute to release the aromas. Stir in the tomato paste to blend with the onions, fry 1 to 2 minutes, then add the stock, bulgur and lentils. Cover and simmer until bulgur and lentils are thoroughly cooked and soup is thickened, about 30 to 40 minutes, stirring occasionally.

Step 2

Remove from heat, stir in half of the herbs and sprinkle the remaining half over the soup. Serve immediately with yogurt to garnish.
