Preheat your oven to 375°F (190°C) and grease a 9x13-inch baking pan with olive oil.

Roll the pizza dough into a rectangle about ¼-inch thick and press it into the greased pan.

In a large mixing bowl, combine spinach, cream cheese, mozzarella, Parmesan, garlic powder, salt, and pepper; mix until creamy.

Spread the spinach mixture evenly over the dough in the baking pan.

Bake for 25-30 minutes until the dough is golden brown and the cheese is bubbly.

Let the pan cool for about 10 minutes before cutting into squares.

Garnish with fresh parsley and diced green bell pepper before serving.

Serve warm and enjoy!
