rules for sloppy joes?

Were you aware there were rules to making sloppy joes? LOL...
Today, while chatting to a friend on facebook, I was trying to think what we could have for dinner. My friend thought of sloppy joes...I mentioned I didn't have any hamburger buns. She said, "You can use bread. There's no set rules for sloppy joes, anything goes. Do people not know that? " LOL...of course I thought it was funny...so of course I thought I'd make it a blog post...we need entertainment around here some days...so that's your entertainment for the day...doesn't take much for me to be amused...lol :P
