Notes
Choosing produce: Look for broccoli and cauliflower heads that are firm and free from discoloration. Pre-cut florets work well for a time-saver.Drying tip: Dry vegetables thoroughly after washing to prevent excess water in the salad.Texture preference: The salad is naturally crunchy, but you can blanch or steam the broccoli and cauliflower lightly if you prefer a softer texture.Make-ahead: Prep the vegetables and dressing up to 2 days ahead and store separately to keep the salad fresh.Flavor swaps: This recipe is flexible—try different vinegars, cheeses, dried fruits, nuts, or even add bacon to make it your own.Dressing to taste: Start with part of the dressing, toss, and add more as needed to avoid an overly heavy coating.
