I personally am all about the sauce, though not necessarily ketchup and bacon but I think it should be on the side so I can have as much as I want and other people dont have to have to have too much. When I was little, if your went out to eat and your meal came with a salad, they brought this little dressing thing that had blue cheese, thousand island and french and you got to pick which one you wanted and how much to put on your salad..... I LOVED that. I would divide my salad in three and put a little of each!
Personally I'd put syrup on a bacon sandwich. If I only had ketchup I'd put it in.
If you want to eat rubbers with your sandwich, more power to you.
on the side please. ketchup on bacon is criminal!
ruins both ketchup AND bacon!
