Stir in egg, salt, and pepper. Blend in enough flour to make a fairly stiff dough. Turn dough out on a well floured board. Knead lightly.
Divide dough in half. Shape each half into a long thin roll, the thickness of a breadstick. With a knife dipped in flour, cut into bite-size pieces.
Place a few gnocchi in boiling water. As the gnocchi rise to the top of the pot, remove them with a slotted spoon. Repeat until all are cooked.
