Re-vamped Spicy Chicken Sandwiches with Cilantro-Lime Mayo

I made THIS recipe again tonight, but seeing as how we're on a strict diet, I had to find a lower carb/calorie way of doing it. Here's what needs to be changed:

-Don't marinate or bread the chicken, just season with salt and pepper
-Use fat free mayo. Seriously you won't notice the difference
- Add a few drops of Tobasco to the mayo to get a bite of a kick still. 5 drops or so
- Ditch the bun. It's a little messier, but still FANTASTICALLY good
Oh and just for good measure I now add 1t or so of soy sauce to the mayo. Very tasty
