Old topic, new ideas!
My absolute favorite snack when I'm being "good" on Atkins is "pepperoni chips" - take thinly sliced pepperoni (the Hormel "sack" type works well for this) and layer on a paper towel lined plate, then nuke for about 40 seconds depending on the strength of your microwave. It might take a few tries, but when they're "right" they'll be something you may have almost forgotten about... "crispy." Not chewy, not crunchy - but honest-to-goodness crispy. They are WONDERFUL for dipping into guacamole or sour cream. Oh, they're really good with cream cheese and green onions, as well.
As far as pork rinds go - don't just try one brand. I detest the Frito-Lay "Bakenetts" but LOVE the Turkey Creek brand. They are a cut and half above anything else, IMO.
One thing that satisfies my rare sweet/creamy cravings is a "mock" coke-float made with diet coke (I prefer diet vanilla coke or Pepsi One), a splash of SF DaVinci vanilla coffee flavoring "syrup" and a splash of heavy (aka whipping) cream. It tastes exactly like the "bottom" of a coke float - the good creamy/coke part.
I tend to keep it simple, staying away from too many pre-packaged items, so some of my favorite recipes are bizarre, to say the least. [WARNING TO NON-LOW-CARBERS --- gross factor ahead! LOL] You can grind unflavored pork rinds in a food processor until they reach a bread crumb consistency, and use them for a LOT of things. One of the "freakiest" is "french toast" make by making a stiff batter of eggs, heavy cream, those "bread crumbs," SF sweetener to taste, and cinnamon. Simply mix and drop onto a hot, buttered skillet and voila, "french toast." This, honestly, tastes like french toast with bacon or sausage on the same plate. With just a bit of SF syrup and butter, it's great for breakfast or a snack.
I do believe I've picked up that you're a Southerner from other posts, so I'm assuming salmon croquettes were part of your culinary bag somewhere along the way, and you can make absolutely fantastic salmon croquettes by using the pork rinds instead of corn meal and flour. No, really. Like BETTER than the "real stuff." Ditto for meatloaf, though that's hard to justify as a "snack" to anyone but low-carbers. ;-)
Are you generally a "salty/crunchy" snacker, or a sweet/creamy snacker? If I know that, I can suggest other ideas. (Not all nearly as scary as the pork rind stuff. But you have to understand, I started low-carbing over six years ago, when the ingredients list was pretty slim for us!)
By the way... that was about 5 1/2 years and 40lbs ago. I reached my goal weight in 2000 and have stayed within 5 lbs of that goal ever since. I pretty much eat what I want now - but what I want tends to involve a lot less white food.
