1-Preheat the oven to 350 degrees Fahrenheit to get everything set for baking.

2-Whisk the 8 eggs until well combined, then mix in the 1/3 cup whole milk, 1 teaspoon Italian seasoning, 1/2 teaspoon salt, 1/2 teaspoon black pepper, and 1/4 teaspoon ground cayenne pepper if you’re using it; set the mixture aside.

3-Heat 1 tablespoon olive oil in a 10-12 inch cast iron or oven-safe nonstick skillet over medium-low heat to prepare the base.

4-Sauté the 1 chopped onion for 3-4 minutes until it’s soft and translucent, building a flavorful foundation.

5-Add the 1 cup fresh spinach, 1 cup halved cherry tomatoes, and 3 minced garlic cloves; cook for 2 minutes until the spinach wilts and the garlic becomes aromatic.

6-Sprinkle the 1 cup grated Pecorino Romano cheese evenly over the vegetables and let it melt slightly for that cheesy goodness.

7-Pour the egg mixture over the vegetables, tilting the pan to distribute it evenly for uniform cooking.

8-Place the skillet in the oven and bake for 20 minutes, or until the center is set and the edges turn golden brown.

9-Optionally, broil for 1-2 minutes to brown the top for extra crispiness.

10-Remove from the oven and let it sit for at least 5 minutes before serving to allow flavors to settle.
