I made these for lunch today and they were a big hit with my boys! Greg even came into the kitchen to tell me again during clean up that he liked them. I can't remember the last time that happened! Anyway, it's a modified Pioneer Woman recipe. Here: http://thepioneerwoman.com/cooking/2010/07/16-minute-meal-3-mini-meatball-sandwiches/ is her recipe for mini meatball sandwiches. Thanks to a suggestion from a friend, I just made bigger meatballs and put it on sub bread instead. It was YUM-O and a good recipe for fall! Let me know if you try them!
