Stuffed potatoes in foil on the grill

Wash the potatoes and wrap in aluminium foil. Bake for about 40 minutes on a preheated grill. Rotate occasionally. Meanwhile, peel the carrots and grate them coarsely. Wash the sprouts and leave to drain. Stir the sour cream to get a smooth mixture. Remove the potatoes from the foil, open the top and fill each with 2 tablespoons of sour cream. Sprinkle grated carrots and alpha alpha sprouts (wheat germ, bean sprouts, ...) over it. Cut the butter with herbs into 8 slices and put 2 slices on each potato.
