•In a large bowl, combine the eggs, 3/4 cup pizza sauce, bread crumbs, onion, green pepper, oregano, garlic, salt and pepper. Crumble beef and sausage over mixture and mix well.
On a piece of parchment paper, pat beef mixture into a 12-in. x 10-in. rectangle. Layer with ham, 1-1/2 cups cheese and mushrooms over beef mixture to within 1 in. of edges. Roll up jelly-roll style, starting with a short side and peeling parchment paper away as you roll. Seal seam and ends. Place seam side down in a greased 13-in. x 9-in. baking dish; brush with remaining pizza sauce
Bake, uncovered, at 375° for 1 hour. Sprinkle with cheese. Bake 15-20 minutes longer or until no pink remains and a meat thermometer reads 160°. Using two large spatulas, carefully transfer meat loaf to a serving platter
