Fantastically Delicious: Baked Bean & Hot Dog Casserole

This is the recipe for one of my FAVORITE Summer Casserole dishes.  My Aunt use to make it all the time and it tastes like my childhood Summer.
I make this recipe multiple times during the Summer and for the first time this Summer on Wednesday night after my closet assault. I burned my arm on my oven (I still have a little burn mark on my arm) and turned my inferno like apartment into a freaking 5-alarm situation. But its so good that I had a bowl at 11:30pm after it had cooled down before I went to bed, THAT's how good it is!
So here it is, I'll make it again this week so I can add a picture..

2 1/2 Cups of baked beans (I prefer Bush's Baked Beans)
