Creating Tzatziki Chicken Pizza is straightforward when you follow these simple steps:

1. Prepare the Marinade: In a bowl, whisk together olive oil, lemon juice, oregano, garlic powder, salt, and pepper.
2. Marinate the Chicken: Add the chicken breasts to the marinade. Let them soak for at least 15 minutes (up to 30 minutes for more flavor).
3. Make the Tzatziki Sauce: In another bowl, combine Greek yogurt, diced cucumber, olive oil, lemon juice, minced garlic, and salt. Mix thoroughly and set aside in the refrigerator.
4. Cook the Chicken: Preheat a grill pan or skillet over medium heat. Cook the marinated chicken for about 6-7 minutes on each side or until fully cooked. Let it rest before slicing into strips.
5. Preheat the Oven: While the chicken rests, preheat your oven to 475°F (245°C).
6. Assemble the Pizza: On your pizza crust, spread a layer of tzatziki sauce to your liking. Top with shredded mozzarella cheese, sliced chicken, red onion, cherry tomatoes, and olives.
7. Bake: Place the pizza in the oven and bake for about 12-15 minutes or until the cheese is bubbly and golden.
8. Add Finishing Touches: Once baked, remove the pizza from the oven. Drizzle with extra tzatziki sauce and top with fresh arugula if desired.
9. Slice and Serve: Allow to cool slightly before slicing. Serve warm.

These steps pave the way for a stress-free and enjoyable cooking experience, ensuring that your Tzatziki Chicken Pizza turns out perfectly each time!
