Combine vinegar, peanut butter, soy sauce, vegetable oil, sesame oil, to taste, sugar and ginger in the bowl of a food processor fitted with a steel blade and process until smooth. Toss 1 1/2 cups of the peanut butter mixture with the chicken tenders in a bowl until the chicken is well coated. Spread the chicken out in a baking pan in a single layer. Bake until the tenders are firm to the touch, about 30 minutes. Let cool.
Thread a skewer into each tender. Arrange on a platter and garnish with sesame seeds and chopped herbs. Put the remaining sauce into a small bowl and serve.
