This spinach and feta pie is one of my family's favorite weeknight meals. While this would be good as a brunch dish, it's easy and filling and more often than not, we eat it for dinner. I don't add any salt as the feta and parmesan bring enough to the dish alone. This is great warm, right after it comes out of the oven, and it is fantastic for lunch leftovers - cold or reheated. Served with some roasted potatoes or a salad, this is a wonderful, comforting meal!
