We fry collards with bacon or other terrible things... why not simulate the same? For this side dish I rehydrated some dried oyster mushrooms, diced them up, and sauteed them with garlic and liquid smoke. I then used these smoky little bits as a base for my sauteed collards. This was a fantastic variation on the garlicky collards I make all the time.
