1 loaf French bread, sliced lengthwise
1/2 pound ground beef
1/4 cup chopped ripe olives
1/8 tsp. pepper
3/4 tsp. salt
1/4 tsp. crushed oregano
1-1/2 tsp. chopped chives or finely diced onion
1/4 cup grated Parmesan or Romano cheese
1 can (6 oz.) tomato paste
6 slices (1 oz. ea.) Mozzerella cheese

Split French bread into halves, horizontally. Combine beef, olives, pepper, salt, oregano, chives, Romano cheese and tomato paste. Spread 1/2 of mixture over each cut side of the two bread halves. Place loaves, meat side up, on a cookie sheet and bake at 350 deg. for 25 min. Remove from oven. Cut cheese slices in half, diagonally. Slightly overlap 6 cheese triangles on each half loaf. Return to oven until cheese starts to soften. Cut each loaf crosswise into serving size portions.
Note: I usually brown and crumble the beef before mixing with the other topping ingredients and can cut down on the baking time until just heated through-this keeps the bread a little softer.
