Take a glass or a cookie cutter and cut a large circle on the bread slices. You can choose to keep it square as well and not cut the bread.
Finely chop capsicum or bell peppers. Discard tomato seeds and finely chop the tomato.
Apply butter on both sides of each slice.
Now sprinkle chopped tomatoes and capsicum on each slice. Sprinkle salt and pepper.
Sprinkle grated cheese over this.
Heat a frying pan or skillet or any grill pan and place the slices carefully on the hot pan.
Lower the heat from medium to low. Cover and let the cheese melt and the bottoms crisp up.
When almost done, sprinkle chilli flakes, oregano seasoning and a few torn-up basil leaves and serve immediately.
