Crustless Spinach Pie

1 (10 ounce) package frozen, chopped spinach
4 tablespoons butter, melted
3 eggs, lightly beaten
1/2 teaspoon salt
1/8 teaspoon pepper
8 ounces cottage cheese
1/2 cup grated mozzarella cheese

Thaw and drain spinach. It is important that you remove the water from the spinach. You will need to actually squeeze the water out. Combine spinach with remaining ingredients. Spoon into a greased pie plate or quiche dish. Bake at 350 degrees for 30 minutes.
