I'm SO dealing with this right now (I'm craving a big ol' deli sandwich - my substitute will be a reasonable veggie sandwich tomorrow for lunch).
I am not sure what diet you are following, or what foods you are allowing yourself, but here are some suggestions with some recipe links:
Kale Chips (I've made these. They are great!)
Salsa & Baby Carrots
Mug of Bullion soup
Almonds or other salted nuts-
but not too many!
Hummus with Celery
How about just a quick all-veggie stir fry and be a little heavy handed with the soy sauce
Tomato and Cucumber Greek Salad with 1 oz non-fat feta and capers - salty goodness! I don't have my recipe for this in my blog, but happy to pass it on to you if you are interested
If cooking isn't your thing, maybe you can try some flavored rice chips that I see in the chip section sometimes.
