Have you tried pepperoni as a snack? It's rather salty!

You can fry them up in a skillet or throw some in the oven until they are crispy. Let them cool and then you can have pepperoni chips! (Haven't checked the sodium content on this though...might not be exactly what you're looking for, but it's an idea.)

Dill pickles usually satisfy my salty cravings...or dishes with vinegar. (Here again, be careful of the sodium content in some pickles.)

Unsalted peanuts help cure my salty tooth! I have to be careful though, because a serving is about 30 peanuts. But strangely enough, the UNSALTED peanuts usually do the trick. (Odd, isn't it?)

If you think of any other ideas, then let me know! I need cravings for my salty tooth too!
