Peel the sweet potato, cut it into slices about 1 cm thick and brush lightly with olive oil and salt. Bake on a baking tray in the oven at 200°C until soft. Wash the European strawberries, remove the middle part and cut into slices. Cut the goat's cream cheese into slices as well. Mix salt, pepper, olive oil and balsamic vinegar (and basil if desired) and put it on the goat's cream cheese - let it steep a little. Chop fresh mint into fine threads. Arrange the sweet potato toast on a plate, first put the rocket and then the slices of goat's cream cheese on top, garnish with the strawberry slices and the mint threads.
