First make your stir fry sauce: in a medium bowl, whisk together the soy sauce, water, rice wine vinegar, honey, brown sugar, garlic, ginger and arrowroot starch (or cornstarch). Set aside.
Add 1/2 tablespoon sesame oil to a deep skillet and place over medium heat. Add diced chicken breast and cook until no longer pink, about 5-8 minutes. Once cooked, transfer meat to a bowl and set aside. Keep the heat in the pan.
In the same pan, add the remaining ½ tablespoon sesame oil. Add in bell pepper chunks, onion chunks and broccoli. Cook, stirring frequently for 5-8 minutes until broccoli is slightly tender but still has a bite.
Stir in pineapple and cooked chicken breast. Pour sauce over and bring to a slight simmer then reduce heat to low and cook for an additional 2-4 minutes until sauce begins to thicken.
Serve with brown rice, coconut rice or quinoa for a healthy dinner. Garnish with scallions.
