For the dough, mix flour, eggs, milk, mineral water and salt with a whisk until smooth, allow the dough to swell for about 30 minutes. For the sauce, wash the herbs and chop them coarsely (put some parsley aside for garnishing).
Mix yoghurt, lemon juice and chopped herbs, season with herbal salt and pepper. Roast sesame seeds in a dry pan until golden brown. Clean and peel the radish and cut or slice it finely.
Wash the tomatoes, remove the stalk and cut the tomatoes into slices. Sort the sprouts, wash and drain. Heat some oil in a coated pan. Fry six thin pancakes one after the other until golden brown and keep warm.
Place a pancake on a serving dish. Alternately place some tomato and radish slices on top, sprinkle with some of the sprouts. Cover with a second pancake. Do the same with the remaining pancakes, tomato and radish slices and sprouts.
Place a few slices of tomato and radish on the top of the pancake to garnish. Garnish with parsley and sprinkle with sesame seeds. Serve with herb sauce.
