The first time I ever had a Po'boy was in NOLA. This recipe is just as good if you can't get there. It is so tasty and yummy. I can't believe how good it is. I made it for my family and they loved it. They couldn't get enough! Make sure you have enough napkins around! This recipe is perfect to make in slow cooker for those days your just too busy or its too hot outside. I hope you enjoy it!

This recipe is more labor intensive than your normal Crock Pot recipe but the outcome is worth the effort.  We can see preparing this one for a tailgate. Our only suggestion is to add more meat because it will go fast!
