So we're throwing down a killer flank steak on the grill tomorrow for steak sandwiches. Crispy lettuce, garden tomatoes, quick pickled red onions (and homemade bread and butter pickles) and hot sauce. Figured since we're going all out, we should have a great sandwich roll to go with it. Suggestions for your favorite sandwich roll recipe? I've got time to do an overnight starter and pretty much all the ingredients I could possibly need, so hit me with your best idea!
