When you crave a classic mayo-based coleslaw but with less fat and fewer calories, use a judicious amount of mayonnaise combined with lower-fat dairy products, according to recent talk on Chowhound. Use buttermilk, low-fat Greek yogurt, or reduced-fat sour cream as a base, julesrules says, then enrich with mayo a heaping tablespoon at a time, tasting as you go, until it "hits the spot."
Other Chowhounds suggest brightening up lower-fat dressings with vivid elements like cider vinegar or pickle juice and a bit of sugar. A fan of buttermilk dressing for slaw, katecm recommends Smitten Kitchen's broccoli slaw, which jnk calls outrageously good.
