So there is roughly 3g of carbohydrate per pound of sausage. There is roughly 3g of carbohydrate per half cup of cottage cheese. At these levels, carb count is moot.
Check the label on the cottage cheese. Nearly every brand has "modified food starch" included and it doubles the carb count. The best cottage cheese I've found is 2% milkfat from Friendship brand. It has NO additives - no whey, no modified food starch, no gums, etc. It's just cultured milk, cream and salt. The taste is totally different than all other brands, too - MUCH better. If you can find this brand, go for this over the sausage IMO. It's a better quality protein. But honestly, I'd rather have a big tub of Greek yogurt given the option.
