Even people who hate vegetables find pickled vegetables to be a treat. You can pickle anything - onions, summer squash, cauliflower, peas, beans, peppers, beets, carrots, turnips, cabbage, peaches - you name it. People will eat it before it is fully pickled because it tastes good. Here's Perpetual Pickles for you with gardens.
Vegetables (like fruit) are nutritionally borderline-useless, but they can be made to be tasty. Thus far this summer I have produced many half-pints and a couple of quart jars of hot pepper jelly, and about 12 quarts of dilly beans. Waiting for my peaches to ripen to make Peach Chutney. I did not grow cucumbers this year. I forget why.
