In an oven proof dish or large glass loaf pan, put beans, cook the hot dogs on the stove until they are grilled ( you can omit this step I guess, as the hot dogs WILL cook in the beans in the oven )and then cut them up in small thin rounds and add to the beans, along with ketchup and onion powder to taste. Top with brown sugar and place in a 350-375 degree oven until the brown sugar is melted and bubbling. Serve with a green salad.
The number of cans of beans and hot dogs depends on how many people you are serving.
If I used pork and beans, I'd add ketchup and brown sugar if I had it. If I had onions and bacon fat, I'd saute the onions first before adding the seasonings.
Later, I found out that a dash of Worcestershire sauce added a nice kick-especially if I was out of ketchup and waiting on payday. And of course grandma had given me a few cases of baked beans before we moved-so that's what we used.
