VIDEO: One of the latest products to hit the produce aisle is cauliflower “rice”. This is just a head of cauliflower that’s been chopped into pea-size pieces. You can buy it precut, break it down with a knife or do it in small batches in a food processor. It’s the perfect stand-in for starchier carbs like grains, and it can be mashed, like potatoes or blended into a savory dip.
