Cut the French bread in half horizontally and place halves, cut side up, on a broiler pan. Broil 4 inches from heat for about 1-2 minutes or until the bread is lightly toasted. Transfer bread to cookie sheets and set aside.
Turn off broiler and set oven temperature to 350º.
In a large skillet, brown ground beef until thoroughly cooked. Drain off fat.
Stir in tomato paste, green onion, olives, water, salt, oregano, and black pepper.
Cook over medium heat until heated through. Remove from heat and stir in Parmesan cheese.
Top bread halves evenly with the meat mixture.
Top with the tomato slices, green pepper slices and pizza cheese.
