Peel kiwi and bananas. Cut the kiwi in half lengthwise. Cut both into slices. Wash, clean and halve or quarter the strawberries. Mix vanilla dessert and quark. Fill half of the dessert into high dessert glasses.
Spread fruit on top and add the rest of the cream. Sprinkle with the muesli. Decorate with mint or lemon balm leaves if desired.
