What's not to like about sandwiches? Meat, bread, cheese, fruits and veggies, pick what you want so you get what you like.
My typical homemade sandwhich is whole wheat bread, smoked turkey, cheddar cheese, tomatoes, dill pickles, lettuce and either red or white onions. Very, very thin layer of mayo and a enough mustard to add some flavor without taking over.
When I go to the Pita Pit, I get chicken and bacon and most of the same other ingredients except sprouts instead of pickles. And sometimes mushrooms. No mayo needed on a pita though, just the mustard.
