<human>:  What recipe should I make for a potluck dinner party?
<bot>: I suggest you try making a vegetable lasagna. It is easy to make and will please a crowd. The ingredients you need are: olive oil, garlic, onion, mushrooms, roasted bell peppers, tomato sauce, spinach, lasagna noodles, ricotta cheese, mozzarella cheese, and Parmesan cheese. To make the dish, preheat the oven to 350°F. Heat the olive oil in a large skillet over medium heat. Once the oil is hot, add the garlic and onions and sauté until softened, about 5 minutes. Add the mushrooms and roasted bell peppers and sauté for an additional 5 minutes. Stir in the tomato sauce and spinach and cook for another 5 minutes. Grease a 9x13-inch baking dish with some more olive oil. Layer the lasagna noodles, ricotta cheese, mozzarella cheese, and Parmesan cheese in the baking dish. Start with a layer of noodles, followed by some cheese mixture, and alternate layers until all filling and noodles are used up. Place the baking dish in the oven and bake for 45 minutes, or until the top is golden and bubbly. Let the lasagna cool for 10 minutes before serving. Enjoy!
