... Squirt of Tabasco or other good hot sauce or crushed hot pepper Mayonaisse (try a home-made extra-virgin for a funky green-colored [and tasty] one. [making home-made mayo's suprisingly easy]) Light Srinkle of Whole mustard-seeds A Splash of Balsamic Vinegar and/or Squirt of Lime or Lemon (or a few drops of vinegar) (if not already in any of the other condiments) Fresh Pepper
... Spinache Sliced or Diced Fresh Tomatoes (or a good gourmet tomato relish) A little Garlic Fresh Herb sprig or 2, like Basil
Or try a different meat altogether, like a boneless chicken breast or good European sausage (the kind that you buy raw).
For some nice and sexy buns, go to a good bakery and get a good French baguette (regular or even whole wheat or multigrain), cut it in half or thirds width-wise, and then length-wise so
Tasty ascii.
