Mediterranean Zucchini and Tomato Frittata

Preheat oven to 375°F (190°C). If using an air fryer, preheat to 350°F (175°C).
Sauté the zucchini: Heat olive oil in an oven-safe skillet (or air fryer-safe dish) over medium heat. Add zucchini slices and cook for 2-3 minutes until slightly tender. Add minced garlic and cook for another minute.
Prepare the egg mixture: In a bowl, whisk together eggs, milk, oregano, salt, and black pepper. Stir in the Parmesan and half of the feta cheese.
