Heat 1 tablespoon of oil in a large skillet over medium high heat.
Season the chicken with salt and pepper. Add to the pan and stir fry for 5 minutes or until no pink remains. Remove from the pan and set aside.
Add remaining oil and garlic. Cook just until fragrant. Add vegetables and cook until tender-crisp, about 7 minutes.
Move the vegetables to one side of the pan and add stir fry sauce, sesame oil and chili paste along with the chicken. Mix to combine. Cook until heated through, about 2 minutes.
