<human>:  How do I make a lasagna?
<bot>: To make a lasagna, you will need lasagna noodles, an appropriate sauce, cheese or other desired toppings, and an oven. Begin by preheating the oven to 350°F (177°C). Next, spread a layer of sauce on the bottom of a baking dish and layer the uncooked lasagna noodles on top of the sauce. Spread a layer of your desired toppings, followed by additional sauce and cheese. Continue this layering process until you have a few inches remaining in the baking dish. Finally, top your lasagna with any remaining cheese or desired toppings and bake for around 40 minutes, or until the noodles are cooked through.
