Preheat oven to 375 degrees. Line a baking sheet with parchment or a silpat liner.

In a large bowl combine flour with greek yogurt, blending well with a spatula until dough comes together in a shaggy ball.

Turn dough onto counter and knead until dough forms a slightly tacky ball.

Using a knife or a bench scraper divide dough into four equal portions. Roll each portion into ropes about 9 inches long. Shape ropes into bagels and place on lined baking sheets. (Alternatively, roll portions into balls, poke holes in the centers and stretch to form bagel shapes.) Brush with egg wash, if using, and top with any toppings.

Bake at 375 degrees for 20-22 minutes. Increase oven temperature to 500 degrees and bake additional two minutes or until tops are golden brown.
