Have ready the shredded cabbage. If you need to drain it, do so now.
Place the remaining ingredients in a large microwave-safe bowl. The bowl should be small enough to fit in the microwave, and large enough to fit all the cabbage.
Mix the ingredients in the bowl together, then microwave on high for a minute and a half.
Remove the dressing carefully from the microwave, and whisk it thoroughly. It may have turned a brownish color, and that's fine. That's what you want.
Carefully start adding the shredded cabbage, and folding it into the dressing, until all the cabbage is added, and it is all well coated and mixed.
Refrigerate until ready to serve, at least 30 minutes to cool.
Notes
Quick notes Use good mustard for this, the plain yellow will not work. Variations If you are very sensitive to hot spices, omit the cayenne.
