I remember seeing a recipe for cheese crackers. You take the parm cheese and grate it onto a baking sheet and bake it till it's crisp and really thin...only the carbs in the cheese is in those..hardly any carbs but they're crunchy.
Also, thin slices of zuchini on a dehydrator will give you something flat, thin and crispy...you might play with that. That's non-bread but crispy..
Yes, RNY worked for me but it also requires a lot of work from me!
