2) Brush the bread with oil. Place the sandwiches on the hot griddle, cover with a baking sheet and weigh down with a heavy pan to press down the sandwiches, or place them in the sandwich toaster.
3) Cook for 2 minutes, until golden brown. Flip the sandwiches if necessary and cook until the second side is golden brown and the cheese melts, about 2 minutes.
Remove from the heat and serve immediately.
