Stromboli - cooking recipe

Ingredients

1 (1 lb.) loaf frozen white bread dough
1 c. sliced mushrooms
1/2 c. chopped green pepper
1/2 c. sliced onions
1 Tbsp. margarine or butter
1/4 lb. thinly sliced turkey
1/4 lb. thinly sliced ham (preferably red-eyed or old ham)
1/4 lb. thinly sliced Provolone cheese
1 1/2 oz. thinly sliced pepperoni*

Preparation

*I often leave off the pepperoni because it makes the sandwich very greasy.
