Roll out dough and cut into triangles.
Place the longer end of the triangles in a circle onto the pan. Leave a circle in the center with all the triangle points laying over the outside edge of the pan, all the way around the pizza pan, to create a ring of dough triangles.
Spoon in the mashed potatoes on top of the large ends of the triangles.
Spoon in the turkey on top of the large ends of the triangles.
Spoon in the cheese on top of the large ends of the triangles.
Spoon in the green bean casserole (or hot dish) on top of the large ends of the triangles.
Spoon in the stuffing (or dressing) on top of the large ends of the triangles.
Spoon in cranberry sauce on top of the large ends of the triangles.
Pull the pointed edges of the dough triangles up and over the filling.
Use a knife to gently tuck each triangle dough tip underneath the inside end of the ring to secure.
Brush the ring with a good coat of egg wash and sprinkle on some seasonings as desired (pictured is salt, pepper, and sage).
Bake in an oven preheated to 400°F for about 25-30 minutes, or until the ring is nice golden brown.
Cool slightly before slicing and serving.
