Hotdog Spaghetti

This is something close to the spaghetti my mom always made for me. We call 'Napolitan' but since I use hotdog(actually I use bratwurst) n ketchup, I call it 'Hotdog Spaghetti', so it sounds friendly for kids too.
First, boil spaghetti(of course). While boiling spaghetti, slice bratwurst to 1/4in, and slice some onions as well. Then cook them in a wok... don't need any oils. Add frozen bell peppers if you like. Cook well. Add spaghetti. Stir well, and add pasta sauce(in a jar) n some ketchup. Don't need too much... That's all! Easy, cheap, kids friendly menu!
