Define this ball you speak of
I did these with Sugar Free Chocolate Chips last week, Super dense/filling, not horrifically high in carbs per Ball:
Low sugar peanut butter chocolate chip protein bites -
I just did these last night, but laced them with more Sugar Free chocolate chips as well, and used liquid stevia instead of powdered. Haven't tried them yet, will report back. I'm hoping the Flax will effectively have increased their volume for minimal/no carb impact per ball.
Low Carb Peanut Butter Balls - The Low Carb Diet
They are REALLY nice for if you are dying hungry between meals, and much more cost effective than the Atkins or other low-carb snack bars. Things like Celery absolutely do nothing for me when I'm hungry, so I stick with things like this, little packs of assorted nuts (like the Mens Health ones), and Jerky.
