To make a grilled cheese sandwich, start by spreading 1 tablespoon of butter on 2 slices of bread. Then heat a frying pan on medium heat and place in a bread slice, grease side down. Then add 2 slices of cheese and fill it with the other bread slice with the greased side up. Roast the sandwich for 3 minutes before turning it into the pan. Finally, continue cooking for another 2 minutes until the other side is golden and the cheese has melted. For tips on adding extra toppings to your cheese sandwich, like bacon or herbs, read on!
