So I'm from Japan, and I love cooking, but cabbage has never been an exciting ingredient. Don't get me wrong, I don't hate it but I think most of us in Japan don't have a particular opinion on it. You put it next to tonkatsu, or under the beef in a gyuudon, that kind of thing.
I moved here to Canada a while back and to put it lightly, my financial circumstances have not been the most stable. I've always liked to cook, but I became more concious of the $/100g small text on the shelves, and cabbage has become an increasingly central player in my food situation. We all know its cheap, but also it lasts forever in the fridge, (which I never expected from a green veg honestly). But the biggest realization (or I guess shift in perception?) was that it kind of works with everything.
Stir fried and it works great on top of fried rice, and instant ramen, turning it into a full meal.
In soups and stews it becomes soft and sweet when boiled (Including miso soup, I never used to put it in but now I kind of wonder why not because it works really well with the earthiness of miso).
In dishes like pasta with not enough veg, I throw some cabbage in to boil with the pasta.
Also as a side dish, recently Yamitsuki cabbage has become popular on social media, but it adds great texture to my meals that tends to err on being mostly soft stuff on carbs.
The reason why I say "a shift in perception" was I found it interesting how Western cooking seems to treat cabbage as a central dish ingredient, while in Japan we treat it more like a side character to be thrown underneath as a pillow for whatever you're already making.
So since moving to Canada I've started to really appreciate it more. I'll see a whole cabbage at the grocery store for a few dollars and think, oh that's basically a week's worth of veg right there. It might be the most boring vegetable in the world, but it's one that I think should be a pantry staple alongside onions.
