Skinny Cow Ice-cream!! Now this is really low carb for me. Hardly causes a blip in my blood sugar. It is expensive and only comes in small tubs for single serves.
No grains seem to work for me, think I am not meant to eat them. I use flaxseed meal and almond meal and make my own bread or biscuits.
I have found a cracker type of item in the Asian shop called Bitter Nut. Little discs made from bitter nut only that you fry in hot oil and they puff up like papadams. Great for dips and I sprinkle salt over them when cooked or they are quite bland.
