<human>:  Who invented the recipe for mac and cheese?
<bot>: I’m not sure who invented it, but I can tell you how to make it. First, you need to boil some macaroni noodles in salted water. Then, you can add some butter, milk, and cheese to the noodles and stir until everything is melted. Finally, you can add some more cheese and stir until everything is mixed together.
