Rinse and dry arugula and arrange in serving bowl or platter
top with thinly sliced red onion, fetta and pistachios
Delicately top with pieces of cubed watermelon
For the dressing
In a high-speed blender add shallot, lemon juice/zest, salt/pepper, mustard, honey, and olive oil. Blend of medium speed for 30 seconds. Taste and adjust amount of seasoning and/or oil as necessary (I find that depending on how much juice I get from one lemon, I need to add more/less olive oil to get a consistency I like).
Add chopped basil/mint to the blender and blend on low speed for 15-20 seconds (don't over blend herbs).
Pour dressing into a small glass container.
To finish salad, drizzle a generous amount of the herb vinaigrette on top of watermelon. Toss gently. Garnish with chopped basil and mint. Add additional fetta, pistachios according to personal preference.
Serve and enjoy!
