This was fabulous! Due to a large family I made lots (2 batches in 1 large tray), so I doubled the ricotta cheese (not the other cheeses) and doubled the spinach. I also left out the eggs (due to an allergy) and swapped for 2 TB of milk. I used my own pasta sauce recipe (doubled that too). Served with garlic bread. A great recipe that has no meat and still creates empty plates. Thanks for posting!
