Go for it girlfriend!!  Season your butt off, that's about the only thing that keeps us sane on this thing!  and tho many have said it's best to avoid it...I love salt and use it heavy every day!  Try sea salt, it's awesome!

I also season with salt freely on this diet.  I figure I'm taking in so much water that I'll flush it out. (?)

If you care to use ground beef on beef days (which I do...and I just use the leanest ground sirloin I can find), you could season it with cayenne pepper, cumin and garlic powder, making it kind of like taco meat.  Then eat it with chopped tomatoes and it's almost like a taco salad.  I also added chopped jalapenos to the meat.  On day 6, since veggies are allowed, you could also have lettuce and onions (really, you could probably have them on day 5 too).

I use the following rub on pork chops (it's not a CSD-sanctioned recipe, but I'm sure it's fine...just spicy seasonings, nothing illegal!), and I bet you could use it on chicken too, maybe even a steak...YUMMY!!!  Using all these spices replaces a seasoning packet that would probably have sugar in it.
