A healthy egg frittata including lots of spinach and mozzarella cheese with the creaminess of sour cream.
Preheat oven to 350 degrees.
In a bowl, combine and mix eggs, milk, sour cream, spinach, half of the cheese, salt and pepper.
On low heat, in an oven ready frying pan, cook egg mixture until edges are barely set.
Remove from heat. Sprinkle top with the other half of cheese.
Bake for 20 minutes or until frittata is fully set. NOTE: If using a crust for a quiche instead, bake for 30 minutes or until crust is golden brown and egg frittata is firm and set.
