Break a whole head of cauliflower into small floweretts. Heat 2-3 tbs of peanut or vegetable oil in a wok, add red pepper flakes (as much as you like) and chopped garlic (I use 3-4 cloves but use your discretion). Briefly saute until fragrant but do not brown. Add the cauliflower and saute on high heat for 1-2 minutes. Add half a cup of chicken broth and put on a tight lid. Cook (steam) for 5 minutes or until cauliflower is cooked but still crunchy (it will keep cooking after it is removed from the flame). Add 1-2 tbs of rice vinegar and stir. Add salt to taste and remove from the heat. There should be only a small amount of liquid left on the bottom of the wok.
You could serve this hot or warm but it is best the next day. The combination of crunch, hot pepper, garlic and subtle vinegar taste all work together. Quoting from Taro Okamoto, "Once you taste this dish, you can not eat over-cooked limp cauliflower in a restaurant."
