Chicken Spaghetti Casserole Paleo Style @ A lil Birdie Bakery -- Note from original Pinner, "I used shredded chicken (boil chicken breast for 20min and shred with fork). I sprinkled Parmigiano Reggiano cheese on top and also when served, I sprinkled bacon on top (cut into small pieces and fried). YUM!" -- This could be a Primal replacement for Aunt Viv's Chicken Tetrazinni!!!
