My mom came to the rescue with a recipe when I told her about the terrible mountains of greens in my fridge. Have you ever tasted collard greens raw? Kale reminds me of garnishes, and dandelion greens don't even pretend not to be related to weeds. I persevered and I don't know if it turned out as the recipe intended, but it's actually pretty good. The sauce has a nice depth to it from the wine and capers, and that, along with the tomatoes, really transforms the usual rabbity harshness of greens into well rounded flavors that I can more than just tolerate.
The original recipe called for leaf celery, or chinese celery, which I think is just more leaf, less stalk than the usual celery, and Aleppo pepper, but I couldn't find either so I used regular celery and red pepper flakes. I also substitutued whole canned tomatoes because that's all I had.
Greek Winter Greens
3 bunches greens (I used collards, kale, and dandelion greens)
2 small onions, minced
3/4 c stalks of leaf celery, minced
2 cloves garlic, minced
10 capers, chopped
olive oil
14.5 oz can of crushed tomatoes
1 c wine
3 T mint, chopped
1/2 c leaves of leaf celery, chopped
1/2 c parsley, chopped
zest of 1/2 lemon
juice of 1/2 lemon
Blanch greens by dropping 'em in boiling water for 2 minutes and then plunging immediately into an ice bath. If you use spinach, or other tenderish greens, reduce boiling time as low as 30 seconds. The greens will cook more later, so half done is fine fer now. Drain and chop the greens, you should have about 3 cups at this point. Don't squeeze the liquid from the greens, enough will come out from the chopping; you'll need this vitamin packed juice to thin out the sauce later(I did squeeze and then had to add water later).
Saute garlic, onions, celery and capers in olive oil until soft and caramelized, about 20 minutes(I didn't cook mine long enough, you can tell in the pic). Add wine to deglaze, along with the tomatoes. In hindsight, if I had any anchovies, I'd throw them in too, mmm. Add S&P to taste, be careful capers are salty so you won't need too much salt. Bring to boil, then lower to a simmer for 20 minutes so flavors can mingle. When sauce is yummy, add in the greens, along with the mint, parsley, celery leaves, lemon juice and lemon zest. Simmer a little more to get the sauce flavor into the greens, or until the greens are tender and sauce is the right consistency.

Next time I might play with red wine vinegar in addition to, or instead of the lemon juice, and maybe top it off with some extra virgin olive oil...but it was pretty good for the first time around, and the first dish where I've actually enjoyed all this healthy stuff. You're welcome, digestive system!
