The marinated meats and the pickled veggies are the standout items on this sandwich. In my version, the chicken is soaked in a fish sauce and lime juice marinade. I have a love-hate relationship with fish sauce. I LOVE the distinct flavor that greatly enhances meat, but HATE the putrid odor that seems to linger for hours. DON'T BE TEMPTED TO SKIP THE FISH SAUCE! It is a vital part of Vietnamese cooking. My suggestion with fish sauce is, hold your nose and pour away! The heinous odor will diminish once cooked!
