Foods I have picked up recently that are reasonably low carb:

from TJ's: Tofu patties - yum and only 7 carbs each. Also their Sausage-less Sausage is 6 carbs. Very filling.

The "Smart" products are pretty low carb, too; Smart Dogs are only 2 carbs each. They also have SmartGround, a ground beef sub. I also picked up a faux chorizo, as I like chorizo and eggs. Just hit your local health food store and head for the tofu section. Or ask...they might have it in a different area.
