@JPB,
That looks wonderful, JPB!
Yum.
You know, I've taken to throwing handful of greens into my soups this winter. Right toward the end of the cooking process.
First, I tried a little chopped silverbeet/chard (which I have growing in my garden), then more & more each time. I really, really like it.
But escarole is a complete mystery to me.
I think it might be called "chicory" here. Not sure.
I'm now going to investigate!
