This vegan lentil shepherd's pie is a hearty and comforting meal that's perfect for a cozy night in. To make it, start by sautéing some diced onion, carrot, and celery in a little bit of oil. Add some minced garlic and cook for another minute. Add some vegetable broth, canned diced tomatoes, and dried lentils. Bring to a boil, then reduce the heat and simmer until the lentils are tender. Season with salt, pepper, and your favorite herbs (such as thyme, rosemary, or bay leaves). Top with mashed potatoes, and bake in the oven until golden brown. Serve hot for a satisfying meal.
