Delicious! I adore Chinese cabbage, and bokchoy/pakchoy. One thing I learned from a Chinese Grandma during a cooking program-- was that vegetables were best when they were lightly blanched (though I often skip this step with great results), and then stirfried in neutral oil with garlic, a bit of sugar and salt or soy sauce. If you don't have a wok, you can still get a good char/"wok-hei" just by keeping a pan at high heat and stirring often.
It doesn't take long at all, and this is my favorite way to eat vegetables in a simple, but consistently delicious way. You can also add some chilies while stirfrying, or topping with some chili oil afterwards. Absolutely divine.
Kimchi could also be an option for that Chinese cabbage-- or any other vegetable, as well, since Koreans have a million different recipes for "kimchis" which are used for all kinds of wild plants and herbs. Creating a kimchi fermenting sauce (blending rice flour paste, gochugaru (korean fine red pepper powder), onion, garlic, apple/korean pear, soy sauce/kombu stock (veg replacement for anchovy paste/fish sauce), and ginger) that can be mixed with julienned daikon, green onions, chinese chives, and then layered into your vegetable of choice.
Maangchi has a great recipe for making kimchi, which details how to properly salt and wilt your cabbage, before applying the paste and letting it ferment:
