Spread ¼ cup sauce on bottom of dish. Top with 4 noodles (it’s ok if they overlap)
Add ½ the ricotta cheese, followed by ½ the chicken, ½ the spinach, and ⅓ of the mozzarella. Add another layer of 4 noodles, followed by ½ the remaining sauce the remaining ricotta, chicken, spinach and remaining ½ of the mozzarella
Bake for 40 - 45 min until the top is bubbly and browned.

Recipe Note
Breaking uncooked lasagna noodles evenly can be tricky. To make it easier, soak them in very hot tap water for about 10 min — they’ll still be firm but soft enough to cut with kitchen scissors.
