Kelp noodles
Kelp noodles are mostly prepared in various Asian cuisine as a low-carbohydrate substitute for rice and pasta. They are commonly used in soups, salads, stir-fries and vegetable side dishes. Since they have a neutral taste they take on the flavors of the dishes to which they are added. The noodles can be purchased online or in health food supermarkets, and restaurants are beginning to offer kelp noodles as an alternative to more traditional noodles or rice in their dishes.
