I also enjoy Wasa crackers, but my favourites are definitely low-sodium triscuits (I could literally eat them with anything!) and I also really enjoy Kashi's TLC crackers. The roasted garlic and thyme party crackers are really delicious, although I can only have a couple, and the 7 grain crackers are good too and you can have 15 in a 130 calorie serving.
The biggest problem I have with crackers is the need for cheese!

Thank goodness for Babybel light and Laughing Cow!
