I am a salty snack guy too. Here is a link to a recipe for a crunchy cracker I make with great frequency;
Crackers
I make a double batch of these and keep them in a glass cookie jar where they keep for weeks/months and are readily available when I feel the need for a crunch. My latest favorite is to use a combination of dark chili powder, chipolte chili powder, and habanero chili powder. This produces a cracker with a decided "kick" that I eat either straight or use dip things like egg or ham salad. I used to also put a little dab of peanut butter on them, but I found I could not control/ limit myself when I did that as I have come to recognize that I have an addiction to nuts.
