Scraping the bottom of the barrel for a green or green-like vegetable after a long stretch of not grocery shopping, I did the following:
Mix shredded green cabbage (bagged from Trader Joe’s works fine) with a grated carrot, some diced kosher dill pickle, ground black pepper and a drizzle of the pickle brine.
Let it sit 15 mins or more and it makes a pretty decent tangy side for whatever you happen to be eating, in my case broiled chicken thigh and rice.
