LBI. It’s not necessarily a secret, but many people have no idea that Jimmy John’s cuts out the innards of the bread loaf before they stuff it with your favorite meat and cheese. If you’re a carb fiend, or simply want your sandwich to be a bit more filling, order it LBI, which stands for “leave bread in.”

When ordering a sandwich at Jimmy John’s online, you’ll see an option at your checkout summary to “Leave bread in”. Leaving the bread in means Jimmy John’s won’t scoop out the bread from the top shelf of your sub.
