At the store today I came across a celeriac root. I was reminded that when I lived in Scotland we would mash them up like mashed potatoes and they were DEELISH. They have the the texture of a potato, but are comparably low on carbs because they are actually in the celery family. It has a mild celerly flavor. I thought I would let you folks know they were out there incase you wanted to try them. I'm positive they are fine for Phase 2, and they might even be okay for Phase 1.
I live in a smallish town and I am able to get them a local grocery store. I bet health foods stores would also carry them. I've posted a pic below incase some of you have never seen one. They are ugly, but once peeled are not so bad looking and taste great.
That's OK . . . there are a lot of similarities between the two plans.
Never tried the Celeriac . . . but I do know that over-cooked cauliflower can be mashed and makes a great substitute for potatoes. so now, we hve another option.
