Open each roll, and put half a piece of cheese on each. 

Then hotdog inside that. 

Beans on top of the hotdog. 

Then half of a piece of cheese on top of that. If you want it really cheesy, go ahead with a full piece for top and bottom. It won't mess it up any :) 

Bake until the cheese is melted, and bread is completely toasted (between ten and twenty minutes), on 350 degrees.
