Mix all ingredients in a small bowl, and slowly whisk in the sesame oil until well blended. *Note, you will not need to use all of the dressing for the salad. It packs a punch! Heat 1 tablespoon of oil in a sauté pan over medium heat. Add the red onions and begin to caramelize. When they begin to dry out a little add a splash of red wine vinegar and sugar. Season with thyme, salt and pepper. Toss the salad together with greens, pear, cashews, caramelized red onion, and drizzle with the Miso Ginger Vinaigrette.
