<human>:  How do you make a vegan lasagna?
<bot>: To make a vegan lasagna, start by preheating your oven to 375 degrees Fahrenheit. Then prepare your lasagna noodles according to the instructions on the package. Next, prepare the vegan ricotta cheese by combining vegan cream cheese, vegan mozzarella cheese, minced garlic, nutritional yeast, and lemon juice in a food processor until creamy. For the filling, sauté onion, garlic, mushrooms, and vegan crumbles in a large skillet. Add tomato sauce and season with Italian seasoning, salt, and pepper. Once the vegetables are cooked and the sauce is seasoned, set aside. Assemble the lasagna in a 9x13 inch baking dish. Layer with lasagna noodles, vegan ricotta cheese, vegetable filling, and vegan mozzarella cheese. Repeat the layers. Cover with aluminum foil and bake for 45 minutes. Remove the foil and bake for an additional 15 minutes until golden brown. Let cool for 10-15 minutes before serving. Enjoy!
