Inspiration for today’s Tri-Color Cauliflower Salad came to me at the supermarket.  I was shopping for a few items, when I spotted a display of different colored cauliflower – and that was enough to inspire this recipe!

In addition to the white, orange and green cauliflower we used in this Tri-Color Cauliflower Salad – you can sometimes find purple cauliflower as well.  (I would have bought that for our salad too if I could have!)

These colorful cauliflowers are naturally occurring varieties, and they are said to contain more nutrients than the more common white cauliflower. We didn’t notice a huge difference in taste among the different colors – but some other online articles claim there is a difference in flavor too.

This Tri-Color Cauliflower Salad is simple and delicious – and it makes an ideal side dish to bring to a summer barbecue because it is equally delicious served chilled or at room temperature.  We steamed, then chilled the cauliflower florets – then tossed them with an easy, zesty dressing made with shallots, lemon juice, Dijon mustard, fresh tarragon and capers.

You can, of course, make this Tri-Color Cauliflower Salad using all white cauliflower florets if that is all that you can find at your local market. (It will be equally delicious!)
