Spinach Stuffed Chicken Breasts

I found a similar recipe in a magazine, which called for seasoned spinach only.  It lacked something.  Katie and I played with it and came up with this version which was is so very yummy.  I've used boneless breasts and rolled them up but the bone-in breasts work the best for keeping the filling in the breasts. 


Spinach Stuffed Chicken Breasts
1 10oz bag fresh spinach
1/2 small onion, finely diced
1 tsp garlic, minced
1 8oz. pkg. softened cream cheese
6 4oz. bone in chicken breasts
Alfredo sauce
Cook spinach with 1 tbsp water in covered dish in microwave on HIGH for 5 minutes.  Drain and then squeeze dry.  Rough chop.
Mix spinach with the next three ingredients.  Cut deep slit into side of chicken breasts.  Stuff spinach cheese mix into the breasts and bake at 425 for 40 minutes.  Serve chicken over Pasta with a thin Alfredo sauce to compliment.
