I have been really trying to look at everything I put in my mouth with a real watchfull eye. I'm wondering how many carbs are in things like:

When I get a sandwhich from KFC (don't worry it's tenderoast) and throw out the bun, there's always that 'special sauce'...and if there isn't, I usally ask for some LOL! So how can I tell how many carbs are in these 'sauces' ....that seem to me to be mostly mayo?

Thanks in advance for you thoughts!
