Squeeze out as much moisture from the spinach as you can (use fresh if you have it, but if not can is ok).
Mix together spinach, cottage cheese, eggs, parmesan, salt and pepper in a bowl.
Here is the tricky part. Take your chicken and cut it down the middle of the breast plate and all the way through the back (you can help by trying to break it). Now you have your chicken in two halves.
Turn your chicken breast side up. Loosen the skin from breast and drumsticks by inserting one hand, palm side down. Gently push hand beneath the skin against the meat to loosen the skin.
Try not to tear the skin.
Spoon the spinach mixture into pockets beneath skin.
Place chicken, breast side up, in a roasting pan. Combine olive oil, oregano, rosemary, and thyme and brush it over chicken. Bake, uncovered, at 375 degrees for 1 hour or until chicken is done.
