Pickled veggies are a popular way to preserve vegetables for long-term storage. The two most common pickled veggies are beets and cucumbers. Beets, which have four letters in their name, are a root vegetable that can be pickled in a vinegar-based brine. Cucumbers, also with four letters in their name, are a type of gourd that can be pickled in a variety of different brines. Pickled veggies are a great way to add flavor and texture to salads, sandwiches, and other dishes.
