Preheat oven to 350 degrees.
Cut the round loaf of bread into a checkerboard pattern, cutting almost to the bottom of the loaf, but leaving the bottom intact.
Melt butter and pour over bread, getting it in all the crevices.
Stuff the bread with the mozzarella, Hunt's Petite Diced Tomatoes and sun dried tomatoes, making sure to get into all the cuts.
Sprinkle Italian seasoning on top of the loaf.
Spray a length of aluminum foil with PAM Cooking Spray, Make sure the foil is long enough to wrap around the bread.
