In a small bowl, whisk together ginger, vinegar, lemon juice, and salt.
In a serving bowl, combine scallions, jicama, honeydew, bell pepper, and blueberries. Pour ginger mixture over salad, and toss to combine (salad can be made up to this point 30 minutes ahead of time).
Just before serving, add arugula to salad mixture; drizzle with the oil, and season generously with black pepper.
Absolutely delicious!
Came out good, brought a different, but healthy twist to salad. I used olive oil rather than canola for a healthier fat. I would probably do at least another half recipe for the dressing, not quite enough.
