I have minimal experience with food cutting. But that experience has been universally disgusting.
One of my students used our laser cutter to slice his pizza, because the Pizza Hut guys failed to cut all the way through.
My office was nearly inhabitable, and his pizza tasted like tar.
I assume if you get temperatures EXACTLY right, you can merely cook the food and it is fine. But except for very thin sheets, I doubt you can cut anything and still consider it tasty afterward. But I could easily be wrong.
