Preheat oven to 350 degrees. Place two wonton wrappers in each muffin round, and push down to stick together. Spray with cooking spray, and bake for 8 minutes, or until wrappers are golden.
For the salad, combine cabbage, lettuce, carrot, 2 Tbsp. olive oil, balsamic vinegar, sesame oil, and 1 Tbsp. of soy sauce. Set aside.
To cook the chicken, combine 1 Tbsp. olive oil, chicken breasts, sesame seeds, cornstarch, garlic, sugar, and 1/4 cup soy sauce. Stir until chicken is fully cooked, and the sauce has thickened.
Place a scoop of salad and a scoop of chicken into each salad cup.
Top with diced red onion (optional).
