Italian giardiniera is also called "sotto aceti", which means "under vinegar", a common term for pickled foods. It is typically eaten as an antipasto or with salads. Milder varieties of giardiniera are used for the olive salad in the Muffuletta sandwich. Try on you next sub-type sandwich for a change of pace. Recipe by Donald Link. Note: 2 tablespoons sugar makes for a slightly sweet bite. If you like less sweet and more sour, cut to 1 tablespoon.
