Stir together the Trop50, marmalade, garlic, tamari and bbq sauce in a small bowl. Set aside.
Warm a large non-stick skillet over medium high heat, and spray with non-stick cooking spray. Once it has warmed, place the chicken in the pan.
Allow chicken to brown on one side for about 4 minutes. When that side has a nice golden color, flip the chicken pieces and brown that side for another 4 minutes.
Next, pour the orange sauce over the chicken and allow it to come to a boil. Let it cook for about 4 more minutes, to finish cooking the chicken thoroughly.
In a small bowl, combine 1 tablespoon corn starch with 1 tablespoon water. Mix thoroughly. Add to the chicken, stirring constantly. The mixture will instantly begin to gel up. Continue cooking, stirring the entire time for 1 minute.
Place cooked chicken over rice and pair with steamed stir fry veggies.
