Polfa, I just found something in the store this week. It is a new product in limited test market called LOW CARB BREAD. (It only came out on Monday.) Get this - it has 4 grams of carbs per slice. I don't have the package in front of me but I think the breakdown is 6grams protein/4 grams fat/4 grams carbos. (I'm leaving for Yosemite so I don't have time to cross reference... but I put up the exact numbers on the diet board.) The thing that astounds me about this stuff is it tastes good. It is a little spongier than most breads... but still a very good bread and definitely it makes good sandwiches. (I haven't had time to experiment with other stuff.)
I will call the company next week when I get back and find out when it will be in mass distribution.
