Being diabetic and my wife a bariatric patient, we are low carb almost entirely. Heart of Palm noodles are great way to still enjoy classic pasta dishes, plus Rao's sauces are lower on the carbs. There is low carb soft shell for tacos by Mission brand. I personally use pork rinds in place of alot of my chip options.
