Using fresh broccoli instead of bagged broccoli slaw makes for a sweeter, more flavorful end product. Look for refrigerated sauerkraut either in the deli or by the tofu in your local grocery store (canned lacks probiotics).
Whisk together yogurt, vinegar, oil, honey, miso, garlic, and pepper in a small bowl; set aside.
Trim and peel broccoli stalk. Cut head in half lengthwise. Starting at the crown, thinly slice both halves, including the stalk. (Or fit food processor with large-hole grating disk. Working with a few pieces at a time, push broccoli pieces and stems through food chute until grated.)
Place sliced broccoli, cabbage, red onion, scallions, raisins, and sauerkraut in a large bowl. Add miso-yogurt dressing; toss until evenly coated. Let stand 10 minutes before serving.
