Preheat oven to 325°F. Coat a 9" x 13" baking dish with nonstick cooking spray.

In a shallow dish, combine bread crumbs and Parmesan cheese; mix well. In another shallow dish, combine egg, water, and pepper; mix well. Dip steaks in egg mixture then in bread crumb mixture, coating completely.

In a large skillet, heat oil over medium heat. Add steaks and cook 3 minutes per side. Arrange steaks in baking dish. Top with sauce and bake 15 minutes.

Sprinkle steaks with mozzarella cheese and bake 3 to 5 more minutes, or until the cheese is melted and light golden. Serve immediately.

Place potatoes in a soup pot and add enough water to cover. Bring to a boil over high heat then reduce heat to medium and cook 15 to 20 minutes, or until potatoes are fork-tender; drain and place in a large bowl.
