A longtime dilemna of mine, related to weight loss, is... How to find good snacks, to eat while working, that are rich in protein but not carbs?

And before anyone says "beef jerky", I don't really like it.

Does anyone have any ideas of high-protein, low-carb snacks, besides beef jerky? Note that I'm not looking for something that simply "says" protein on the label but turns out to be mostly carbs with a little protein in it (like many of the "bars" you find at the health food stores), I want to sate my appetite with something that's genuinely mostly protein, to prevent me from wanting to go out to a fast food restaurant for lunch, and to offset the carb intake I normally have for the rest of the day.
