Peel the bananas, cut them into slices and sprinkle them with lemon juice to prevent them from turning brown. Spread 4 slices of bread with fat. Spread 2 slices with nut nougat cream and 2 with cream cheese.
Dab the banana slices dry and place them on the nut nougat cream. Place the cheese coated slices on top and cover with the uncoated bread slices. Cut each bread diagonally into four pieces.
