A mouth watering sandwich you can fill with your favorite sandwich meats and cheese.
Spray counter lightly with non-stick cooking spray. Combine rolls and roll into a 12 inch circle. Place in a sprayed 12 inch deep dish pizza pan. Brush with olive oil and sprinkle with Italian seasoning. Cover with sprayed plastic and let rise until double and bubbly. Remove plastic and press finger tips into the dough to dimple it all over the top. Bake at 450°F 6-8 minutes. Remove from oven and let cool.
With a long serrated knife, carefully slice the circle to separate top from bottom. On bottom, with cut side up, layer salami and Canadian bacon, slightly overlapping, until bottom is covered. Top meat with cheese slices. Bake at 400°F just long enough to melt cheese. Remove from oven and place top of focaccia on top of melted cheese. Slice into pie shaped servings and serve with marinara sauce if desired.
