Dissolve the yeast in the water and let stand for about 5 minutes. Mix the flour with the oat flakes, salt and grains. Knead this mixture with the yeast water and the quark to a dough.
This must be covered in a warm place for at least an hour. Then knead the dough again and shape it into long dough pieces of any size.
Mix the ingredients for sprinkling and lightly press one side of the dough into the mixture. Then cover the dough in a warm place and let it rise for at least 40 minutes.
Bake at 220 ° C (fan oven) for about 30 minutes, until the rolls are lightly brown.
