" cooked greens tend to look like mush"
That was always pretty much my impression of cooked greens too, Cindy! Then I discovered home-grown and home-cooked spinach, beet greens and chard, and discovered they don't have to be that way. They're quick to cook, as well. Now I just need to branch out into more varieties... I have some baby bok choi seeds coming from the beta swap, so that will be a good place to start, I think.
I like cooking chard by chopping up the stems and leaves separately, start with cooking the stem pieces, then towards the end add the leaves and cook just until they're tender. Salt and pepper, and maybe a dash of balsamic vinegar, is all I've ever added, but I'm sure there's room to branch out there, too...
