I love the Liviva Shirataki With Oat Fiber Products. They make this rice substitute and they make it in spaghetti and penne. So low in calories.
Now these products do have a strange texture; it is like a bean thread noodle/a little rubbery. Some people don't like the texture. However, I love it and love even more how low in calories this is.
I add soy sauce or other sauces and spices to give it flavor. Love the Liviva Shirataki with oat fiber products.
You can find this on Amazon but you have to buy 6 of them. The penne or spaghetti you can buy one package at a time.
