Mmmm Mmmm Monday: Philly Beef-Stuffed Sandwich

This is a goodie from Pampered Chef. They suggest you use their 15" round baking stone, but a pizza pan would work just as well. This recipe is great for parties and get-togethers!

Philly Beef-Stuffed Sandwich
1 cup green bell pepper, chopped
3/4 cup onion, chopped
1 tablespoon vegetable oil
2 garlic cloves, pressed
1 teaspoon dried oregano leaves, divided
2 pkgs (10 oz each) refrigerated pizza crust (in the tubes like Pillsbury rolls)
8 oz thinly sliced deli roast beef
8 oz thinly sliced America cheese
1 egg white, lightly beaten
1 tablespoon water

Preheat oven to 400*.
Heat oil in a 10" skillet over med-high heat until hot. Press garlic into pan. Add bell pepper, onion and 1/2 teaspoon oregano. Cook and stir 3-4 minutes or until veggies are crisp-tender. Remove pan from heat.
Unroll one pizza crust onto lightly floured surface. Roll dough out to 12"x9" rectangle. Cover with half the beef, cheese and veggie mixture, leaving 1/2 inch around edges of dough. Starting at the longest side of the rectangle, roll up dough (jelly roll style) and press seam together to seal. Repeat with the remaining crust and filling ingredients.
Place rolls, seam sides down, on baking stone/pan and join the edges together to form a ring, pressing edges together to seal.
In small bowl, combine egg white & water and brush onto the top of the ring. Sprinkle with remaining 1/2 teaspoon of oregano.
Bake for 20-25 minutes or until golden brown. Let stand 10 minutes before slicing.
