Dinner in 20 minutes: Shake 'n' steak, or how to pull off a lean meal where less seems like more

Of all the steak-and-greens recipes I've come across, this one deserves props for being a bit of an oddball. Why coat sirloin with anything besides salt and pepper, you might wonder? To help keep it moist and tender, for one thing. In such a quick-cooking recipe, the lean meat might become tough, or it might not brown properly.
