For the best flavor, use high-quality extra virgin olive oil. Blanching the cauliflower briefly helps to retain its vibrant color and crisp texture. Marinating the cauliflower overnight allows the flavors to fully develop. Feel free to adjust the ingredients and proportions to your liking. For example, you could add other vegetables such as bell peppers or carrots, or substitute a different type of cheese. This salad can be stored in the refrigerator for up to 3 days.
