Divide dough into eight balls and roll out on a floured board. Spread with 1/8 filling and top with 1 slice of provolone. Roll up and seal edges. Place the eight rolls in a circle in a greased and floured 12-inch Dutch oven. Top with mushrooms and more provolone cheese, if desired.
Cook rolls in a 12-inch Dutch oven, using 8 coals on bottom and 10-12 coals on top for about 15 minutes. Remove 2 to 3 coals from the bottom and rotate the lid 1/3 turn and cook about 30 more minutes. The rolls should have the same golden brown color on the top and on the bottom. ENJOY!
