I recently discoverd collard greens and love them. The recipes I've seen for collards call for lengthy cooking, but I braise them on the stovve top for 30 minutes and they're done. I remove the stems from the greens and soak the greens thoroughly because they're full of dirt. I like to cut the greens into strips about 1 inch wide. Then I heat a frying pan, add 1 or 2 cloves of garlic, and after about 30 seconds add the collards, 1 cup of water and a chicken boullion cube. Let the collards braise about 30 minutes. They should be tender and delicious.
if you're like me and never tried collards- give them a try.
