Clean and wash salads. Pluck oak leaf lettuce into bite-sized pieces, cut Batavia into strips. Wash cucumber, cut into slices. Clean, wash and cut the bell peppers into rings.
Clean, wash and quarter radishes. For the marinade season vinegar with salt and pepper. Embezzle oils. Mix the prepared ingredients with the marinade. Cover and let it stand for a while. In the meantime cut the tofu into slices.
Turn one after the other in flour, whisked egg yolk and chopped hazelnuts. Carefully fry in hot fat for about 1 minute on each side. Season salad again and serve with the tofu.
