01 - Heat 2 tablespoons olive oil in a large skillet or wok over medium-high heat until shimmering.
02 - Add chicken strips to the hot pan. Cook for 5–6 minutes, stirring occasionally, until golden brown and cooked through. Remove chicken and set aside on a plate.
03 - Add remaining 1 tablespoon olive oil to the pan. Add onion, bell pepper, and zucchini. Stir fry for 4–5 minutes until vegetables are crisp-tender.
04 - Add minced garlic and dried oregano to the vegetables. Stir constantly for 30 seconds until fragrant, being careful not to burn the garlic.
05 - Return cooked chicken to the pan. Toss everything together for 1–2 minutes until heated through and well combined. Season with salt and pepper to taste. Serve immediately, garnished with fresh parsley and lemon wedges if desired.
