Mile-High Sandwich Round

1 (1-pound) round loaf bread
1/3 c. mayonnaise
1 tsp. dried italian seasoning
1/2 tsp. pepper
1 medium onion, thinly sliced
1 small green pepper, seeded and cut into thin strips
1 stalk of celery, sliced
1 T. olive oil
1 pound of sliced deli ham
1 1/2 c. shredded cheddar-mozzarella cheese blend

Slice off top 1/4 of bread loaf: set aside. Hollow out bottom, leaving a 1/2 inch shell.
Combine mayo, italian seasoning and pepper. Brush half of mixture inside bread shell. Set aside bread shell and remaining mayo mixture.
Cook onion, green pepper, and celery in oil in large skillet over medium-high heat, stirring constantly, about 5 minutes or until tender.
Arrange half of ham in bread shell, and top with half of vegetable mixture; sprinkle with half of cheese. Top with remaining ham; spread remaining mayo mixture over ham. Top with remaining vegetable mixture and cheese. Replace bread top, wrap in foil, and bake at 400 for 30 minutes or until thoroughly heated. Cut into six wedges and serve immediately. This is a very messy sandwich and you may need a knife and fork to eat it, but it is well worth the mess!
