Collard Greens

I am into leafy greens. I got some collard greens, (frozen) and made up this tasty dish of the greens, vegan sausage, dark red kidney beans, mushrooms, onions and garlic saut?ed in a little olive oil. It was good and very healthy.
I found the trick to collard greens is vinegar. They don’t taste good unless you drizzle in a bit of cider vinegar. That seems to bring out their flavor.
I boiled them first, then tossed them into the mixture I had saut?ed. Great source of iron. I sprinkled a bit of Veggie Shreds on top after I put them on the plate. Yum.
