Giardinieraor mixed pickled vegetablesare usually referred to in italy simply as sottaceti, literally meaning "Under vinegar. " They often appear as part of a standard italian antipasto misto, and they also work very well with boiled meats in the winter months. It would be better to store it in several smaller jars, rather than one large one because the contents of an open jar lose their freshness. Select jars with lids that seal well and (optional, but handy) the little plastic mesh depressors that keep the contents of a jar submerged. This recipe does not require processing in a hot water bath because the vinegar-brine solution is all that's necessary in this case to preserve the vegetables; be sure to use a good-quality vinegar for the best results.
