Spinach quiche

A simple and delicious dish that I threw together with frozen spinach, eggs, and some odds and ends of cheese.

5 eggs
1/2 cup milk
1 10 oz. package frozen spinach, thawed, with the water squeezed out
1/3 log of goat cheese (optional)
1/2 cup shredded mozzarella
1/4 cup parmesan
1 bunch scallions, chopped
Salt and pepper

1 sheet of puff pastry, thawed

Place the puff pastry in a pie pan. Mix the other ingredients together, and pour into the pie pan. (You can roll the puff pastry out into a circle; I just lay mine in as a square, without rolling, and fold the corners back on top of the filling.) Bake for 25-35 minutes at 450, or until the middle is no longer jiggly. Let cool 10-15 minutes.
