Mix all ingredients except vegetable oil together and form into 6 patties.
Put oil in a skillet to a depth of a little less than half and inch. Heat over medium heat until a pinch of cornmeal sizzles when dropped in. Put all of the patties in the hot oil and fry for about three minutes per side, or until golden brown. The second side may cook a little more quickly than the first. Drain on paper towels.
Serve with mustard sauce, below.
