Is Melted Cheese Better Than Just Cheese?

If you have a sandwich with melted cheese, it somehow feels like it's less healthy. I feel broken sad when i driak when i eat just regular cheese, not melted. My mam has been doing that since he kid, and i do it for my kid. It's got to be cut in either half or in triangles. Triangles are the best way to dip it. Yoo, where just cheese on a sandwich is just Cheese on a sandwich. Onfali, i would prefer the cheese to be melted.
