Wash your greens using a salad spinner

Cut the orange using the supreme method. See instructions in post above. I provide a link to a video on how to do this, if you do not already know how.

Cut the top off the fennel and save the fronds for later. Cut fennel in half and then in half again so you easily slice on the core. Slice fennel in matchstick size pieces.

I love castelvetrano olives with this salad too but it's optional

In a salad bowl, layer the mixed greens, then the oranges, then the fennel and olives if you are using them.

Add all ingredients (dijon, vinegar, olive oil) to a mixing bowl and whisk them all together. Pour over your salad and enjoy!
