Razz, I know just what you're talking about... I don't keep any of that food in the house. I recently bought a bag of wasabi peas at Trader Joes. I used to eat a whole bag but made it last a week. They're spicy and crunchy but low carb. I also put Tobasco sauce on 97% fat free popcorn for some flavor.
Also: carrot sticks, apple sticks, Ak-Mak crackers with tuna, Fiber One bars.
Some day I hope to have enough self control to have one serving of Cheddar & Sour Cream Ruffles...
