Have you tried Cheeters crackers? They are very good, come in about 10 flavors, cheesy to cinnamon, and are only 1 carb for three crackers. They are pretty big, too.
I have always been a cheese and cracker lover, so these get me through a lot of sticky situations. I been experimanting with new cheeses too, to keep things interesting.
Look them up-they're deffinitly worth it.
A word of caution-there is another brand that looks exactly like Cheeters. I don't remember the name, but they are awful! Don't be fooled!
