In large skillet, brown beef over medium high heat while breaking up into small pieces, until no longer pink and fully done. Drain off any grease.
Add both jars of pizza sauce to beef in skillet. Stir and cook on medium until bubbly.
Slice each bun almost through and spoon beef mixture into the bun. Add cheese on top and seal with plastic wrap. I like to save the bag the rolls came in and place the sealed ones back in there for an extra layer of protection. Place in refrigerator.
When ready to eat, heat individual rolls in microwave for about one minute.
Can be stored in fridge for several days.
