<human>:  Can you help me cook a vegan lasagna?
<bot>: Sure! Start by preheating the oven to 350°F. Spread a layer of vegan ricotta cheese at the bottom of a 9x13 baking dish. Top with a single layer of lasagna noodles, followed by a layer of vegan meat crumbles and vegan cheese. Pour your favorite vegan marinara sauce over the layer. Continue layering noodles, cheese, and meat until the dish is filled—usually three layers will work. Top the lasagna evenly with vegan cheese and bake uncovered for 40 minutes. Let cool for 10–15 minutes before serving. Enjoy your vegan lasagna!
