Cook the lasagna noodles as directed on the box. Lay them out flat on a baking sheet lined with parchment paper. Spray a 9x11 or 9x13 inch baking dish with no stick cooking spray.
Chop or shred the chicken into very small pieces.
In a medium size mixing bowl, place the ricotta and parmesan cheese, 1 cup of the mozzarella, the egg, and the spinach. Stir the ingredients together to combine well. Fold in the chicken. Make sure the ingredients are well combined.
Divide the mixture evenly between the noodles. This recipe will fill 8 noodles well or 6 very full. I start with 2 heaping tablespoons on each. Carefully, spread the mixture the length of the noodle. **A mini spatula works well for doing this. **
Beginning at one end, tightly roll each noodle up. Arrange the roll-ups beside each other in the baking dish.
Prepare the Alfredo Sauce and preheat oven to 350 degrees F.
Place the butter and heavy cream in a large saucepan or skillet. Turn heat on low and stirring constantly, allow this to heat about 2 minutes. Do not boil!
Whisk in the garlic, Italian Seasoning, salt and pepper. Simmer over low heat for 1 minute. Continue to whisk constantly.
Whisk in the parmesan cheese, continue until it is melted. Remove pan from the heat.
Using a ladle, spoon the sauce over all of the roll-ups. Sprinkle remaining mozzarella cheese over the roll-ups.
Spray a sheet of aluminum foil with no stick cooking spray and cover the baking dish. Place in oven and cook for 20 minutes. Remove the foil and continue to cook another 10-15 minutes or until cheese is melted and sauce is slightly bubbling. Serve warm.
