I have found a great healthy alternative to plain bread or rolls for your favorite sandwich.
It is Flatout Flatbread, I buy them at Costco. The multi-grain with flax are excellent tasting are only 100 calories per piece, 2.5g fat, and (get this) provide 8 g or equal to 31% of your daily requirement of recommended fiber.
The Flatout Flatbread gets two thumbs up in my book for being tasty, excellent for you, and relatively inexpensive compared to others that I have tried.
Give it a shot, you will enjoy.
