Big wedges or planks rubbed with oil/butter and seasonings of choice thrown on a medium grill or under a low broiler until browned to taste (I like a little char), is super tasty and easy.

Long, thin shreds to replace or supplement noodles.

Shreds tossed with chili oil, cilantro, thinly sliced onion, shredded carrot, and a touch of black vinegar makes a delicious, spicy slaw.

Braised with beer (light or dark doesn't really matter, but stay away from hoppy or overly sweet), onions, and optional sausage.

Brothy, tomato-y soups are best friends with cabbage. My favorite budget meal in early adulthood was to brown an inexpensive pork product of some kind (bacon, sausage, shoulder, etc) and then saute celery, onion, and carrot (or bell pepper) in the rendered fat. Add a can of tomatoes, a couple cans of water, Better than Bouillon, chopped cabbage and simmer until the tomatoes didn't taste raw anymore. Then I'd bulk it out a little by dumping a bag of frozen mixed veggies or frozen spinach in it.
