The best thing since sliced bread

I think I'm going to eat one of these sandwiches just about every day for the entire summer, and probably beyond that. Yum. Mustard, mayo, cheese, a bit of black pepper, red leaf lettuce, and heaps of tomatoes. Trevi loves this concoction, too, and calls it The Mummy Special. Clara likes a more bare-bones version (cheese and mayo only), but I swear that she would get hooked if I could just get her to try one bite. Breakfast, lunch, dinner...this is an equal-opportunity sandwich. I seriously need to go and make one right this minute.
