parsley root?

[habitat_gardener]

This week I've been thinning out the Italian (flat) parsley that has taken over my garden, some of it with half-inch-thick roots. Coincidentally, I noticed seeds for "parsley root" in one of the catalogs. Does anyone grow parsley root, and how do you use it? I was thinking of using it like parsnips, either roasted or in soups.

I've also harvested lots of mache (before it starts elongating and going to seed) and kale (flowering tops just short of flowering) this week.
