Place potato flakes in a medium-sized bowl. Pour in boiling water and stir until blended. Let cool.

Stir in the beaten 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 the dough in half. Shape each half into a long, thin roll, about the thickness of a breadstick. Cut into bite-sized pieces using a knife dipped in flour.
