This recipe couldn't be much easier, and it's pretty versatile: broccoli is a good accompaniment to almost everything in my opinion. You could probably just add some meat or tofu to this and have a whole main course to serve over rice.
Basically you take your broccoli (I used this thin-stemmed kind that I can't remember the name of, but you can also use cauliflower, broccoli raab, or a terrifying hybrid I never heard of but Bittman suggests called Broccoflower) and cut the tops into florets, then peel the stems and chop them up. Stems are like the chicken wings of broccoli: so often overlooked, but so clearly the best part. Jacques Pepin agrees, so it's true.
Then you heat up some neutral oil over high heat and throw in the broccoli until it's just starting to brown. Add salt, sugar, and stock, then keep stirring until most of the liquid is evaporated--you end up with a slightly thickened sauce. Add soy sauce, and you're done.
Ate this with a salad and roast chicken parts in ginger scallion sauce (David Chang's recipe, not Bittman's). It was a fast, easy meal that felt more like a feast.
