"Create one recipe card for Greek Chicken Kebabs that contains two clearly labeled ingredient sections and one shared method: Version 1 with onion and garlic, and Version 2 without onion and garlic. Keep both versions dairy-free, gluten-free, corn-free, nut-free, shellfish-free, beginner-friendly, quick (15-30 min), and suitable for 3 servings. Use imperial units only. Include chicken, cremini mushrooms, red bell pepper, cherry tomatoes, kalamata olives, olive oil, lemon juice, oregano, thyme, rosemary in the onion/garlic version, and omit onion and garlic in the non-onion/non-garlic version while keeping it flavorful with lemon, oregano, thyme, salt, and black pepper. Make it clear that the two versions are separate ingredient lists within one recipe card."
