Preheat your oven to 200°C and line a baking sheet with parchment paper.
Mix the flour, yogurt and salt in a bowl and kneed until a dough forms.
Lightly flour your work surface and take the dough out of the bowl.
Flatten the dough and form a disc.
Cut the dough in four equal pieces.
Roll each piece into a log and shape that log into a bagel.
Transfer to the prepared baking sheet.
Beat the egg and brush the top of the bagels with the egg wash.
Generously sprinkle with the seed mix or topping of your choice.
Bake ca. 25 minutes or until golden brown.
