For the Spicy Slaw:
Sprinkle the salt on the cabbage and toss. Let stand for 20 minutes.
For the slaw, mix the fish sauce, vinegar, chile flakes, garlic, ginger, sugar, scallions and sesame seeds in a bowl.
Rinse the cabbage under cold water, then squeeze the excess water out. In a bowl, toss the cabbage with the fish sauce mixture until well-coated.
