1/2 teaspoon salt
1/4 teaspoon black pepper
1/4 teaspoon ground nutmeg

Directions

Preheat your oven to 375°F (190°C).
Roll out the pie crust and fit it into a 9-inch pie dish. Trim any excess dough and crimp the edges.
In a large bowl, whisk together the eggs, milk, salt, pepper, and nutmeg until well combined.
Stir in the ricotta cheese, chopped spinach, shredded mozzarella, and grated Parmesan. Mix until everything is evenly distributed.
Pour the filling into the prepared pie crust, spreading it out evenly.
Place the quiche in the preheated oven and bake for 35-40 minutes, or until the top is golden brown and the center is set.
Allow the quiche to cool for about 10 minutes before slicing and serving.
