If you like huge, tasty sandwiches then this is the perfect sandwich for you. WhatWillyCook walks you through his favorite steak sandwich dish. With a succulent unusual to medium steak, jammy red onions, blue cheese, mustard-y mayo and some green things (for health) this sandwich is so great absolutely nothing else will taste the very same once again. You can rely on Willy since Willy understands best, most likely. #sandwich #steak #food #whatwillycook Register for MUNCHIES here:…
