Preheat oven to 375°F (190°C).
Lightly grease a pie dish or small baking dish.
In a large bowl, whisk the eggs and milk until smooth.
Stir in cottage cheese and shredded mozzarella.
Fold in chopped spinach and season with salt, pepper, and any herbs you like.
Pour the mixture into the prepared dish.
Bake for 35–40 minutes, or until the center is set and the top is golden.
Let it cool for 5–10 minutes before slicing.
