Collard greens in tacos?

Yes, you can put anything in a taco.  Tacos with greens apparently aren't all that uncommon, though it's not something I've ever seen in a restaurant.  Last year I made some breakfast tacos with beet greens and egg, and they were pretty good.  Week before last I had some folks over for tacos and end-of-curriculum celebration, and I wanted to have a vegetarian taco available along with the beef and chicken, and also, I needed to use up some of the greens from the week 3 CSA box - along with all the lettuce, there was a bunch of collards.  I found this recipe for Braised Greens Tacos on Serious Eats, and decided to give it a try.  I used a Vidalia onion in place of the red onion, and blistered the cherry tomatoes for the salsa under the broiler rather than a frying pan.  I used water instead of chicken or veggie broth for the braise (I wanted to keep it vegan, and I didn't have veggie broth).  I found that I needed about 15 minutes of braising to get the collards to a tenderness I liked.  Surprisingly tasty!  Also good with scrambled eggs in a tortilla. No pics of an actual taco, but here is the filling in the pan:
