This is my favorite salad to make for family gatherings and potlucks. It's very easy and so much healthier than potato salad. It can be made ahead--in fact, it's at its best after about 12-24 hours of marinating. It keeps well in the fridge for about 2-4 days before it starts to deteriorate in quality. Prep time is estimated; you can buy pre-washed broccoli florets and cauliflowerettes to speed preparation. Cooking time is minimum marinating time.
