I changed my strategy on shopping. I buy only vegetables I can ferment in canning jars. Easier portion control. Zero waste. Buy what's on sale or plentiful in season. I even put my apple peels, potato peels, carrots peels, beet tops, etc...into a canning jar to ferment with garlic, hot pepper, and herbs. (American Kim-Chee)
So you only eat fermented vegetables? At home at least/
