<human>:  How do I make lasagna?
<bot>: To make lasagna, you will need lasagna noodles, a sauce of your choice, cheese, and cooked meat if desired. Preheat your oven to 375 degrees F (190 degrees C). Grease a 9x13 inch baking dish. Layer the bottom of the dish with a layer of the noodles. Spread a layer of the sauce and add a layer of the cheese. Repeat layers until all ingredients are used, ending with a layer of cheese. Bake the lasagna in the preheated oven for 25 to 30 minutes, or until the top is golden and bubbly. Allow to cool before serving. Enjoy!
