Steps
1. Spread the butter on the slices of bread.
2. On each slice of bread, layer on the sliced tomato, shredded cheese, and top it off with a teaspoon of mayonnaise.
3. Heat up a non-stick pan on medium heat. Place the sandwich in the pan and grill each side for about 2 minutes, or till cheese has melted and bread has golden-brown colour.
4. Serve and enjoy!
