One good Rice Substitute for Asians doing OMAD Keto is Cauliflower Rice. Well it basically cauliflower chopped or processed until it's the size of cooked rice up to the size of corn kernels. It's then panfried with some white pepper and a bit of salt until cooked. It's delicious and has a lot of vitamins such as C, K and Folate. And it only has about 25-30 calories per cup unlike rice which has 200 plus calories per cup.
