Heat 1 tbsp olive oil in a large skillet over medium-high heat.
Add sliced chicken breast and cook until golden brown and cooked through. Remove from skillet and set aside.
In the same skillet, add remaining olive oil and sauté garlic and ginger until fragrant.
Add the bell peppers, carrot, and broccoli. Stir-fry for about 3-4 minutes until crisp-tender.
Return the cooked chicken to the skillet.
In a small bowl, whisk together soy sauce, honey, sesame oil, and red pepper flakes.
Pour the sauce over the chicken and vegetables. Stir to combine.
Add the cornstarch mixture and stir until the sauce thickens, about 1-2 minutes.
Serve over cooked rice and garnish with sesame seeds and sliced green onions.
