12 wonton wrappers (if this is your first time make some extras)
Preheat oven to 400'
While the oven is preheating bring a large pot of water to the boil and drop in half of the wonton wrappers, one at a time. Boil for 1 to 2 minutes and remove with a slotted spoon. Rinse under cold water and lightly coat with vegetable spray to prevent them from sticking together. Place on a piece of parchment paper or waxed paper that has been lightly coated with vegetable spray so they do not touch. Repeat process with remaining wrappers.
Blend the ricotta cheese, spinach, garlic, egg, basil, oregano and nutmeg in a large bowl. Season with salt and pepper if desired.
Lightly coat a large casserole dish with vegetable spray. Arrange four wrapper as the base of each portion, taking care they don't touch. Top each with about 2 tablespoons of the ricotta mixture and spread with the back of a spoon to cover the wrapper. Top with one ounce of the mozzarella cheese divided between all four portions. Place about 2 tablespoons of marinara sauce on each portion. Add another wonton wrapper and repeat process. Place the final wonton wrapper on top and spoon an additionally 2 tablespoons of sauce on each and divide the remaining 2 ounces of mozzarella cheese between the portions. Sprinkle each with a teaspoon of Parmesan cheese. Bake for about 20 to 30 minutes or until they are bubbly hot and the cheese has melted.
