Apply butter on all the bread slices, place it on a nonstick pan, and toast it on one side on a medium flame.

Now flip the side and place cheese slices, halved and seedless red grapes on the bread slices and toast it on a medium flame till the cheese melts.

Sprinkle some salt and pepper on it and garnish with fresh rosemary.

Drizzle some olive oil just before serving these beauties.
