Combine everything well. Season with salt & pepper. Let simmer for 20' put the lid on, checking and stirring occasionally. *adjust liquid as needed, adding water in small intervals (you don't want this to dry, but you also don't want to make soup).

Put the baking dish in the oven in the middle rack and let it cook for 15'-20' (or until the filling is bubbling and the top is golden brown).(I don't like it overcook) Let it rest for 5 minutes before serving.
