Beef Roll Mozzarella

Combine meat, salt, pepper, onion, egg, and bread crumbs in large bowl. Drain mushrooms; reserve. Add enough water to mushroom liquid to make 1/2 cup; add to meat mixture. Mix lightly, just until well combined.

Press mixture into a 14x19" rectangle on a piece of wax paper. Sprinkle surface with mozzarella, leaving a 1/2" border. Roll up, jelly-roll fashion starting with one of the short sides. Place, seam side down in a 13x9" baking dish. Combine tomato sauce with vermouth. Spread 1/2 the sauce over the roll.

Bake at 375 degrees F for 45 minutes. Combine remaining sauce with reserved mushrooms; spread over roll; bake 10 minutes longer. Lift onto heated platter with 2 wide spatulas.
