Mix Vinaigrette: In a Pyrek with a pour spout, whisk together all of the vinaigrette ingredients until emulsified.
Prep the Salad: In a large bowl, add the arugula and watermelon and give a quick mix. Add the mint and feta and mix.
Dress the Salad: Pour half of the vinaigrette over the salad and mix and then finish with the other half and mix well. Enjoy!
