I love cabbage for this. It’ll last a long time too!

I put it in a freezer bag in the fridge after each use. It’ll brown a little on the edge, but it’s easy enough to shave off.

Then in the summer I’ll plant the bottom part in the garden. I’ve currently got a grocery store cabbage that has sprouted two new ones and another one I just finished to plant today. I also do this with celery
