I purchase raw nuts (cashews, almonds, walnuts) in bulk, soak them overnight, and store in the freezer. This allows me to make any cream sauce in the Vitamix in about 5 minutes, no prep time required.
I must be honest. I am not a huge fan of pasta. Even the high protein varieties feel heavy in my system—less is more. My favorite version of this recipe is to halve the pasta and double the cauliflower. I've kept it as written as this is the most kid friendly version. However, my kids didn't notice when the switch the second time I made it. So play away with the ratios.
