Shirataki noodles are thin, translucent, gelatinous traditional Japanese noodles made from the konjac yam. They have zero carbs or calories and take on the taste of whatever sauce you put on them. Though not a pure substitute for pasta as far as taste, they’re a very close one as far as texture and satisfaction.
You can find the no-calorie noodles in the refrigerated section of your produce aisle, usually next to the tofu. They’re packed in water. Drain and rinse well before using.
