In a large bowl combine cheeses, salt & pepper, 1/2 cup of flour and beaten egg and egg yolk. Stir to blend.
Line a baking sheet with parchment paper and dust with flour.
Dust your hands and pinch dough into roll into 2" balls (estimated)
Lay balls on flour dusted baking sheet. Dust balls and roll so that they do not stick to parchment.
Bring a large pot of water to boil, add a huge pinch of kosher salt and add balls in batches. (I cooked about 12 a batch)
Balls will rise to top, but continue cooking for a total of 5-6 minutes.
Remove with slotted spoon to serving bowl that is filled with sauce.
Toss to coat and serve with a sprinkling of Parmesan cheese and parsley
