Using a large pizza pan, open packages of crescent rolls. Lay the first package in a large circle, connecting the wide part of the crescent roll in the center. Top with second package of crescents. Use fingertips to combine and create an indentation to add italian beef.
Fill indentation with Italian Beef. Top with giardiniera and shredded cheese. Roll triangles up over filling, using hands to spread dough as needed.
Bake in a 375 degree oven for 25-30 minutes. While baking, heat au jus. If using my homemade slow cooker recipe, use the excess juice in the crock pot. If using Papa Charlie's Italian Beef, heat up the remaining au jus in the container, in a sauce pan until simmering.
