Riced Cauliflower is very easy to make. Simply run it through your food processor or use a cheese grater to break it up. What I do with this recipe is start the bacon frying, then start ricing the cauliflower. Then I put the cauliflower in a microwave safe bowl, cover and microwave for 5 minutes. No water is needed. While that is cooking I break up the broccoli and get it ready to steam. When the cauliflower comes out I microwave the broccoli for 5 minutes.
When it comes to shredding chicken or any other meat, I HIGHLY suggest getting a pair of Bear Paws. They are hands down the best tools I’ve used for shredding meat.
