Time saving tips for this recipe

This is already a quick and easy recipe, but there are a couple of ways to make it even easier. First, instead of “ricing” a head of cauliflower in the food processor, you could grab a bag of pre-riced cauliflower from the store. Second, grab some pre-peeled and deveined shrimp, so you don’t have to do any of that work yourself!
