In a cast iron skillet (or nonstick skillet) over medium-high heat, cook the ground beef until browned and fully cooked, breaking it apart as it cooks; drain any excess grease.

While it simmers, prepare bread. I usually just simply pour oil in the skillet, then mop it up with the bread (do this with both slices so they are both ready). Add sloppy joe mixture, then cheese and remaining slice of bread on top.
