A food processor makes quick work of chopping ingredients for this red lentil soup that takes inspiration from the Anglo-Indian classic Mulligatawny. Apples add a touch of sweetness, chicken makes it extra-hearty, and coconut milk brings it all together.
Pulse the scallions, jalapeno, ginger, cilantro and garlic in a food processor until chopped. With the motor running, add the apples, a few pieces at a time, until chopped.
Cook the curry powder in a Dutch oven or large pot over medium-high heat, stirring, until lightly toasted, about 1 minute. Whisk in the coconut milk until smooth; cook until reduced by half, about 5 minutes. Add the apple-scallion mixture and 1/2 teaspoon salt. Cook, stirring, until thickened, about 5 more minutes.
Stir in the chicken broth and lentils. Bring to a boil, then reduce the heat to medium low and simmer until the lentils are tender and broken down, about 15 minutes. Add the chicken and simmer until cooked through, about 6 minutes. Season with salt and pepper and garnish with cilantro.
