With a sharp knife, cut the crusts off each piece of bread.
Using a rolling pin, flatten each piece of bread.
Place a piece of cheese on the bread and carefully roll up the cheese inside the bread. Repeat with the remaining cheese and bread pieces.
In a medium skillet, melt butter over medium heat. Place roll-ups on the skillet and let cook on one side (about 2-3 minutes). Carefully flip the roll-ups over and cook on the other side for another 2-3 minutes.
Remove roll-ups from heat and serve.
As we were making these, we found that the best bread was a really soft white bread. If the bread is not super soft, the roll-up tends to just fall apart or easily rip.
The best cheese was the American cheese singles - it rolled up inside the bread the very easiest. However, I know that is not the healthiest choice, so experiment with different cheeses and see what works for you! 🙂
