Ratatouille is a classic French dish that is perfect for a vegetarian dinner. Start by sautéing onions, garlic, eggplant, zucchini, and bell peppers in the Dutch oven. Pour in canned tomatoes and let the ratatouille simmer until the vegetables are cooked through. Season with salt, pepper, and your favorite herbs and spices. Serve with crusty bread and a glass of red wine for a satisfying and flavorful meal.
