I do love my greens, and I love this dish. It can be spicy, warm, tangy, or even creamy. Use lots of greens to make this a full mean for Meatless Monday, or reduce the amounts for a side dish.
While I’ve noted that you can use any type of greens you wish, I find I get the most satisfaction from spinach and chard. They are “wetter”, meaning you don’t need to add a lot of extra liquid while cooking down the greens. Kale and collard greens will need more liquid to braise until suitably tender.
Note: once you’ve made this dish once, you will crave it all the time!
