Preheat oven to 400º F.
In medium-sized frying pan, add ground beef, peppers and onion. Sauté beef, breaking up as you go along, until crumbled and done through. Drain grease if needed.
Stir in jar of sauce, (my homemade or your own favorite), and simmer for at least 5 minutes, stirring occasionally. *Longer if the store-bought sauce is a bit runny. (Longer simmering will cook out any excess water/liquid that they add, and make a nice, thick sauce, which is what we want.)
Cook hotdogs however you want. (Grill, boil, steam, microwave, deep-fry, or fry in a pan with a little butter.)
Open buns widely, and lightly spread insides with garlic herb butter. Place into oven on a baking sheet for 1 - 2 minutes to lightly toast.
Remove from oven, and place a hotdog inside of each. Spoon sauce over tops and sprinkle each with lots of shredded cheese. Pop back into the oven and bake for about 7 - 10 minutes until cheese is melted. Serve hot and enjoy!
