This was a very good one-dish meal! I used a store-bought can of spaghetti sauce but think this would be better jazzed up with some peppers and spices. I bbq'd the chicken for added flavour. I had a little bit of sticking on my glass pan so I would suggest either spraying with cooking spray or spreading a small amount of sauce around the pan before adding the shells. To get supper on the table quickly, I did all the prep the night before and stored covered in the fridge overnight.
