Talk about fast food! You can prepare this side salad in less than 5 minutes. Then chill it while you make the rest of your meal. Fennel seeds add a distinctive licorice flavor to an otherwise basic slaw. The seeds may be omitted, if desired.
Place coleslaw in a serving bowl. Combine mayonnaise and next 3 ingredients in a small bowl, stirring well with a whisk. Spoon dressing over coleslaw, and toss well. Sprinkle with fennel seeds. Cover and chill at least 1 hour.
