1 refrigerated pie crust (or homemade, if preferred)
1 cup fresh spinach, chopped
1/2 cup crumbled feta cheese
1/4 cup mozzarella cheese, shredded
4 large eggs
1 cup milk
1/2 teaspoon salt
1/4 teaspoon black pepper
1/4 teaspoon dried oregano
Preheat your oven to 375°F.
Place the pie crust in a 9-inch pie dish and press it firmly against the bottom and sides. Trim off any excess crust.
In a medium-sized bowl, whisk together the eggs, milk, salt, black pepper, and dried oregano (if using) until thoroughly combined.
Layer the chopped spinach evenly over the pie crust.
Sprinkle the crumbled feta cheese and shredded mozzarella cheese on top of the spinach.
Slowly pour the egg mixture over the spinach and cheese, filling the crust completely.
Use a fork or spoon to gently mix the ingredients, ensuring the egg mixture is evenly distributed throughout the filling.
Place the quiche in the preheated oven and bake for approximately 35 to 40 minutes, or until the center is set and the top is golden brown.
Remove the quiche from the oven and allow it to cool for a few minutes before slicing and serving.
