Lentil stew is a hearty and comforting dish that is perfect for a cold day. Sauté onions, garlic, and carrots in a pot, then add lentils, vegetable broth, and your favorite herbs and spices. Let it simmer until the lentils are tender and the flavors have melded together. You can also add other vegetables like potatoes, celery, or tomatoes to make it heartier. Serve with crusty bread for a satisfying meal.
