Notes
OPTIONS AND VARIATIONS
Use a bag of pre-shredded cabbage and carrots as a time saver.
Looking to lighten things up? Use plain greek yogurt in place of the mayonnaise.
Don't like creamy coleslaw? Try leaving out the mayonnaise and replacing it with 2 teaspoons of extra virgin olive oil for a vinaigrette coleslaw.
