In a small roaster, pour both cans of Pork & Beans, discarding any pieces of fat, into the roaster. Next, drain 3/4 of the liquid out of the butter beans and pour the rest into the roaster. Add both cans of tomato sauce, brown sugar and stir. Bake uncovered at 375 degrees for 1 1/2 -2 hours stirring occasionally. While beans are cooking, cut bacon in half and fry until crispy. Drain bacon of grease but do not drain grease from frying pan. Cut hot dogs into coins and cook in bacon grease. Be careful when doing this as the grease will splatter. I like to carefully add one spoonful of hot dogs to the grease before adding the rest. This keeps the grease from splattering so much. Fry hot dogs until browned and caramelized. Drain hot dogs on a paper towel from the grease. Right before serving baked beans add hot dogs and bacon.
