This was a throw-things-together-and-see-what-happens pie. Turned out well! I sauteed one 250g packet frozen spinach with some chopped leek, then mixed it with two 250g tubs of light/low-fat ricotta, a little grated Parmesan, whatever was left of a packet of grated mozzarella (about 250g), two lightly beaten eggs and some pepper. Baked it puff pastry for about 40 minutes. With the leftover cheese mixture I made “rolls” and baked them for about 25 minutes.
