Yes, those are pigs in a blanket around the outer perimeter. These "Double Roll Pies" are available at Japanese Pizza Huts according to Geeks Are Sexy. And presumably "Double Roll" refers to the waist augmentation that results from just looking at one of these cholesterol bombs.
I guess it's just like a party in a box, though. Put the pizza out and have people eat pigs in a blanket for appetizer, and then they can move on to the pizza and meat for a main course.
It's a wonder that Japan isn't the fattest nation on earth...
