<human>:  What is the best way to make a spinach quiche?
<bot>: The best way to make a spinach quiche is to preheat your oven to 350 degrees F (175 degrees C). Grease a 9-inch pie plate with butter. In a large bowl, mix together 2 cups chopped fresh spinach, 8 ounces of crumbled feta cheese, 1/2 cup of shredded mozzarella cheese, 3 eggs, 1/2 cup of heavy cream, and 1/4 teaspoon of nutmeg. Pour the mixture into the prepared pie plate and bake for 35 to 40 minutes, or until the top is golden brown. Enjoy!
