Heat 1 tablespoon of oil in a large pan over medium high heat. Add chicken and stir fry until cooked through. Transfer chicken to a plate.
Heat the remaining olive oil in the pan. Add vegetables to the pan. Add salt, pepper, garlic powder, and Italian seasoning. Stir fry 3 – 4 minutes until the vegetables are just cooked through.
Add the chicken back to the pan along with the white wine and lemon juice and stir fry for an additional 2 – 3 minutes.
