-* I used boneless chicken breasts, boneless thigh pieces are also delicious.-Before heating the sauce to drizzle on top of the chicken, I add about 1-2 tablespoons balsamic vinegar for color and flavor. I like the way it adds a little more intense flavor to the sauce.-If you would like to make this dish ahead, it's easy to do so!Marinate the chicken. Follow directions for cooking. When the chicken is cooked, carefully place the skewers in a 9x13 pan and refrigerate.When ready to serve, remove from refrigerator, let sit on counter for about 30 minutes. If serving warm, heat oven to 375 degrees. Heat uncovered on a cookie sheet in a single layer for about 3-5 minutes. Remove, and drizzle with sauce, garnish with sesame seeds and green onions and serve.
