Fettucine Alfredo is one of the most beloved comfort food dishes in America, and we made a version perfect for vegan, gluten-free, low-carb, and keto babes. You’ll find it tastes cheesy and fills you up. While you may have seen a lot of cashew cream sauces on Pinterest, we opted for macadamia nuts because they’re low in carbs (1.2 net grams per ounce). This particular recipe will only set you back roughly 11.4 net grams of carbs per serving, well within your allotted 50 grams for the day.
