Cook bacon until crisp and drain, reserving 2 tablespoons drippings. Crumble bacon; set aside. Cook onion in the reserved drippings until onion is tender not brown. In the bowl combine the onion, bacon, Worcestershire sauce, salt, mustard and oregano; add ground beef; mix well.

Top each burger with a few slices of zucchini and 1 tomato slice. Spoon sauce on top. Sprinkle with Parmesan cheese. Broil 1 minute more. Serve on rolls. Makes 4 servings.
