Low carb snacks??!!

Angeled eggs (they are deviled eggs, except you use sour cream instead of mayo) red and orange bell peppers with a flavored cream cheesed spread on it or celery with cream cheese, Parmesan crisps

I second the beef jerky. I make my own, with lean London broil. The commercial stuff has sugar, but your own can be sugar free and much better tasting. All it requires is a dehydrator or a convection oven that can heat at around 170 fahrenheit or 77 celsius and a rack to hang the strips on.
