Cut crust off the slices of bread. This makes the bread easier to roll and will hold the shape better.
2. Step
Flatten slices of bread with a rolling pin.
3. Step
Layer the slices of cheese on top of each slice of bread so that the cheese is offset from the bread by about 1 inch (2 ½ cm) vertically. Other fillings can be added here if desired.
4. Step
Roll each slice of bread with cheese vertically as tightly as possible without cracking the bread. Gently squeeze each roll to maintain its shape and set down on its seam.
5. Step
Melt the butter in a pan. Grill each roll starting with the seam side down on the hot pan.
