Spread a generous amount of softened butter on one side of each slice of fresh sandwich bread.

Arrange the thinly sliced cucumber and tomato on top of two slices of bread, ensuring they cover the entire surface.

Season the cucumber and tomato slices with salt and pepper according to taste.

Place the remaining slices of bread on top of the cucumber and tomato slices, buttered side facing down, to form sandwiches.

Press down gently on the sandwiches to secure the filling.

Using a sharp knife, carefully cut each sandwich diagonally to create triangular halves.

Serve the fresh tomato and cucumber sandwiches immediately, or wrap them in parchment paper or cling film for later enjoyment.
