Cover each hard-boiled egg with a sausage patty, pressing to cover and seal.
Combine flour, salt and pepper. Roll eggs in flour mixture, then in beaten eggs and bread crumbs.
Heat one inch of oil in a saucepan over medium-high heat. Cook eggs, a few at a time, in hot oil for 10 minutes, or until golden on all sides.

Serve chilled with mustard, if desired.
