How to Make It
Preheat the oven to 450°. Prick the eggplant all over, set it in a small baking dish and roast for about 40 minutes, turning once or twice, until very tender. Let cool.
Meanwhile, in a large saucepan, heat 2 tablespoons of the oil until shimmering. Add the cumin seeds and crushed red pepper and stir over high heat just until fragrant, about 1 minute. Add the garlic and cook until lightly browned, about 30 seconds. Stir in the lentils and water. Season lightly with salt and bring to a boil. Cover and simmer over low heat until the lentils are tender but not mushy and the liquid is absorbed, about 40 minutes. Transfer the lentils to a serving bowl.
Scoop the flesh from the eggplant and chop it. Drain the eggplant in a fine sieve to remove any excess liquid. Add the eggplant to the lentils along with the lemon juice, mint, parsley and the remaining 1/4 cup of oil; season with salt and pepper. Serve warm or at room temperature with naan and yogurt.
