French Bread Pizza

1 1/2 lb. ground beef (I used some ground beef, some pepperoni slices and triangled pieces of canadian bacon)
1/2 tsp garlic powder (use only if using all 1 1/2 lb. of ground beef)
1/2 tsp salt (use only if using all 1 1/2 lb. of ground beef)
2 loaves (8 oz each) French bread, halved lengthwise
1 jar (8 oz) process cheese sauce
1 can (4 oz) mushroom stems and pieces, drained (opt)
1 can chopped olives (opt)
1 c. chopped green onions (I sauteed sliced green bell peppers and yellow onion)
1 1/2 c. pizza sauce
1/2 c. grated Parmesan cheese
4 c. (16 oz) shredded part-skim mozzarella cheese

1. In a skillet cook ground beef until no longer pink; drain. Stir in garlic powder and salt.

2. Place each bread half on a large piece of heavy duty foil. Spread with cheese sauce. Top with beef mixture, mushrooms, olives and onions. Drizzle with pizza sauce. Top with Parmesan and mozzarella cheeses. Wrap and freeze. May be frozen for up to 3 months.

3. To bake: Unwrap loaves and thaw on baking sheets in the refrigerator. Bake at 350 for 18 minutes or until cheese is melted.
