2 cups plain or Greek yogurt may be substituted for the Ricotta cheese, although it may cause the lasagna to be less firm; be sure to allow the lasagna time to cool and set up before serving. The spinach layer is optional (but I recommend it, since the spinach almost completely disappears!). Shredded carrots may be omitted if desired (the lasagna will still stay intact).
