Andrea Can Cook demonstrates how to make pigs in a blanket using crescent rolls. First, preheat the oven to 375 degrees. To make pigs in a blanket, you will need a tube of crescent rolls and hot dogs. Unfold the crescent rolls onto a baking sheet. Roll up the hot dogs in the crescent roll triangles by placing the hot dogs on the wide part of the triangle and rolling them up towards the tip. Bake the pigs in the blanket for 12 minutes at 375 degrees. For another tasty treat, you can put cheese inside the left over crescent rolls and sprinkle garlic salt on top.
