Steps
1. Begin by heating a skillet over medium heat.
2. Add the sausage link to the skillet and cook until browned and cooked through, about 5-7 minutes.
3. While the sausage is cooking, butter one side of your sandwich roll or slice of bread.
4. Once the sausage is cooked, place the cheese slice on top and cover the skillet for a minute to let the cheese melt.
5. Remove the sausage and cheese from the skillet and place it on the unbuttered side of the roll.
6. Spread mayonnaise on the other side of the roll, then add lettuce and tomato slices if desired.
7. Close the sandwich and optionally return it to the skillet, pressing down slightly, to toast both sides to your liking.
8. Slice the sandwich in half and enjoy your cheesy sausage delight!
