Begin by cutting 1 pound of chicken breasts into bite-sized pieces. Mince 2 cloves of garlic and grate about 1 teaspoon of fresh ginger. Zest and juice one orange, setting both aside separately. Chop 3 green onions for garnish.
In a bowl, whisk together 2 tablespoons soy sauce, 1 tablespoon honey, 1 tablespoon sesame oil, the freshly squeezed orange juice, orange zest, minced garlic, and grated ginger to make the orange sesame sauce.
Season the chicken pieces lightly with salt and pepper. In a small bowl, combine 1 tablespoon cornstarch and 2 tablespoons water to create a slurry. Toss the chicken pieces in this mixture until lightly coated.
Heat 1-2 tablespoons of vegetable oil in a large skillet or wok over medium-high heat. Add the chicken pieces and cook for about 5-6 minutes, stirring occasionally, until golden brown and cooked through. Remove the chicken from the skillet and set aside.
Lower the heat to medium and pour the prepared orange sesame sauce into the same skillet. Let it simmer for 2-3 minutes until it starts to thicken. Return the chicken to the skillet and toss well to coat every piece in the sticky sauce.
Remove from heat and sprinkle 2 tablespoons of toasted sesame seeds and the chopped green onions over the chicken. Serve immediately over a bed of warm cooked rice or quinoa.
