Mmm, mystery greens

So many greens in this week's CSA box, by two days later I had forgotten exactly what they are all called. I recognized the kale and napa cabbage right away in the fridge, but what kind of green was I using today when I made a salad for a potluck? Tatsoi? Komatsuna? Some kind of choi?

I told everyone who liked the salad that I think it was komatsuna. For anyone here who is going to try to reproduce this recipe, sorry if it's not komatsuna and you get different results.

Mystery Greens Salad
at least 6 servings

1 large bunch komatsuna (or whatever brassica leaf I was using), about two handfuls
2 Tbsp olive oil
2 Tbsp lemon juice
pinch chili powder
handful of raisins
handful of roasted salted almonds

Cut greens into thin ribbons with a knife and place in a bowl. Whisk together the oil, lemon juice and chili powder and pour over the greens. Toss to dress, then garnish with raisins and almonds. Can be made a few hours ahead.
