1 pound Italian sausage, casings removed
1 pound fresh spinach
1 cup shredded Mozzarella cheese
1 pound dough
1 tablespoon extra virgin olive oil
Black pepper, freshly ground to taste

Cook sausage in large skillet until browned, drain fat, add spinach. Cook until spinach wilts, 3 minutes. Cool slightly.

Roll out dough on lightly floured surface to a 10×12 inch rectangle. Transfer dough to an oiled baking sheet. Spoon sausage mixture evenly over half of the dough lengthwise, leaving a 3/4 inch border. Cover with shredded cheese. Fold dough over filling. Press and seal edges of dough with fork.

Brush top of dough with olive oil. Sprinkle with pepper to taste. Make several slits in top of dough with knife to release steam. Bake in lower third of preheated 400° oven until well browned, 15 to 20 minutes.
