To cook the millet on the stove:
Bring 2 cups of water to a boil in a medium pot. Add the millet. Lower the heat and cover and simmer until all the water is absorbed, about 20 minutes.
Spread the cooked millet out on a rimmed baking sheet lined with parchment paper (for easier clean up.) Allow the millet to cool for abut 15 minutes until room temperature.
Place the cooled millet in a large salad bowl with the orange, carrots, and basil.
Add the Dijon Mustard Dressing ingredients to a small jar or bowl and shake or whisk until well combined.
Pour the dressing over the salad. Toss well to coat. Serve immediately or cover and refrigerate for later.
Before cutting off the orange peel in order to segment it, be sure to zest the orange and reserve the zest for the dressing.This salad can be made in advance and covered and refrigerated until you're ready to eat.
