Heat the oil in a frying pan. Add Nasi Goreng and steam for about 6 minutes, turning occasionally. In the meantime, clean and wash the paksoi and separate 6 leaves (if necessary, use the remaining leaves differently).
Cut out the stalk and blanch the leaves in boiling water for about 1/2 minute. Rinse under cold water. Carefully spread leaves on the work surface and place 1 heaped tablespoon of Nasi Goreng in the middle of each leaf.
Smooth out a little and fold the sides of the leaves slightly over it. Then roll up and tie up with kitchen string. Arrange the rest of the Nasi Goreng and the rolls on a plate and serve with a slice of lemon and lemon balm to taste.
