The easiest is the quick canning method with brine.
Cut them in spears or slices or leave whole, put in sterilized jars, make a brine (many recipes), pour over top to within 1/2-1 inch of top, clean top, put on sterilized lids and rings. Put in water bath, bring to a boil for 10 minutes, take out, let cool.
I'm sure someone will have a great recipe for you. Do you like dill pickles or sweet or other?
