Whisk together the orange juice, lemon juice, shallots, honey, salt, and pepper.
Add the olive oil and shake, shake, shake. If not using right away, store the dressing (covered) in the refrigerator. I use a ball jar to make, shake and store the dressing.
Place the arugula, watermelon, feta, and mint in a large bowl.
Drizzle with enough dressing to coat the greens lightly and toss it all together.
Serve and Enjoy!
