Roast Beef Sandwich With Creamy Chimichurri Sauce

"Sandwiches and I have a troubled relationship. I don't generally eat them, because sometimes they are unkind to me. So, the thing about it is, if you see me eating a sandwich, it's because that sandwich is extraordinary. And this here Ultimate Roast Beef Sandwich with Creamy Chimichurri Sauce most definitely qualifies. Fresh baked bread piled high with bright green lettuce, thick sliced deli cheese, mounds of rare roast beef, fresh tomatoes, and zingy red onion, then drenched with creamy chimichurri sauce and served with a pickle. This is the kind of sandwich that wins husbands. And wives, annnnnnd wives."
