For a low-fat version, you can sub half of the cashews with 1/2 cup (90g) of white great Northern beans. So, you would add 75g of cashews and 90g of beans in this low-fat version. I tested this version and it was still yummy. Although, it does make it slightly less creamy and a very mild bean taste. It is not very detectable over pasta though. If you are concerned of a bean taste, use all cashews.
