Step 1

Heat oil in a medium saucepan over medium heat. Add onion and cook, stirring occasionally, until softened, about 3 minutes. Add garlic, turmeric, ginger and cumin; cook, stirring constantly, until fragrant, about 1 minute. Stir in broth, lentils, chickpeas and salt. Bring to a boil over medium-high heat. Reduce heat to medium-low to maintain a simmer; cover and cook, stirring occasionally, until the lentils are tender, 30 to 40 minutes.

Step 2

Remove from heat and stir in spinach, green beans and lemon juice, stirring until the spinach wilts and the green beans are heated through, about 1 minute. Ladle the soup into 6 bowls; sprinkle with crushed red pepper and garnish with a sprig of cilantro, if desired.
