I agree in principle that it would be best if I stayed close to unprocessed foods altogether. However, since I'm pretty new, I seem to need to prove to myself that there is a low-carb version of just about anything I could crave, so I have been trying a wide variety of products.
Judy's sugar free (maltitol) nut brittles are exceptional. Greenbeanz online has pretty decent prices on the 10-oz. packages of Judy's coconut deluxe nut brittle and mixed nut brittle. Both kinds are out of this world. It's good to keep my consumption to a minimum, though, because it's easy for me to get more maltitol than my gut thinks is good.
Ditto on the Gram's Gourmet sweet cinnamon butter pork rinds. I was always grossed out at the thought of pork rinds but Gram's turned me around. You can also make them at home with plain pork rinds, cinnamon, Splenda & butter---yum.
