Personally, one of my favourite easy meals is doing a quick stir-fry of shredded cabbage with onions / mushrooms / garlic / random-other-veggies, some leftover cooked meat, and using either a purchased hoisin sauce or some leftover homemade sauce (I always make extra meats and sauces and freeze in portions).
Another easy option is to do "deconstructed cabbage rolls", where you just cook all of the ingredients together using shredded cabbage (can do it in a casserole dish in the oven, using the slow-cooker or pressure cooker, or even just saute on the stove) and skipping the "roll" part.
I also enjoy cabbage as a cooked side dish. To me, it tastes great whether steamed in chunks, or roasted in chunks (coat in a little oil and add spices to taste), or sliced in to "steaks" and grilled (again - a bit of oil and spice to taste).
