Gross. I've been making my own pickles, pretty easy to do, and you can pickle any random vegetable, really. Whatever's cheapest. Might be worth looking into, it's super fast and you can do it in any plastic bucket. Even cheaper if you do lactoferment.

As always it's a time:money tradeoff tho. But this one takes like 5 minutes with a mandolin and a bucket. I cut up the bucket lid and weight it down with a couple food cans to keep the veggies under the pickling liquid.
