Using a sharp knife, make slits in the chicken breasts width-wise that are about ¾ inches apart, making sure not to cut all the way down through the bottom of the chicken breast.
Season the chicken with salt and pepper.
In a bowl mix the spinach and ricotta cheese together.
Season with nutmeg.
Stuff the spinach mixture in the slits of the chicken, filling it with the volume you want (I tend to over stuff things)
Sprinkle the grated Parmesan and Cheddar cheese over the stuffed chicken breasts (optional)
Place each chicken breast onto a baking tray lined with parchment paper or a greased baking dish.
Bake in the preheated oven for 25-30 minutes, or until the chicken is cooked through.
Eat and enjoy
