Assemble the sandwich and place it in a hot, lightly greased griddle pan. Place a frying pan on top of the sandwich and weigh it down with a couple of cans.
Cook it for about 3 minutes until the crust starts to brown and the cheese melts through the pores of the bread. Flip it a couple of times so it cooks evenly, but make sure you don’t overcook it, or you won’t be able to taste all the flavours.
