To make a vegan coconut lentil curry with sweet potatoes, you'll need: 1 medium sweet potato; 1 large red lentil; 2 tablespoons coconut milk; 1/2 teaspoon kosher salt. Cook the lentils until they're just tender, about 15 minutes. Add the coconut cream, salt, and pepper to taste. Cover the pot and cook on medium-low heat for 5 to 10 minutes, stirring occasionally. Remove the pan from the heat and stir in 1/4 cup chopped cilantro. Serve warm.
