Acorn squash boasts incredible benefits from the high levels of vitamin A & C it contains. Improved skin health and eyesight are just a few health benefits linked to the consumption of vitamin A, and a heightened immune system is the result of consuming vitamin C.

More veggies! Cauliflower is kind of strange because it isn't colourful so you wouldn't think it to be one of the healthiest foods for you, but alas it is packed to the brim with health benefits! Antioxidants are in abundance which will aid in keeping you cancer-free by stopping free radicals in their tracks. Cauliflower also has high levels of vitamin K which keeps your blood circulating at a healthy rate, therefore ensuring your cardiovascular system is in tip top shape.

Once our acorn squash and broccoli are roasted we can set that aside until we are ready to plate our pasta. At this point the cauliflower should almost be soft enough to transfer to the food processor.

Once the cauliflower has softened you can transfer everything in the saucepan to a food processor. Add your nutritional yeast and lemon juice and blend the sauce until it is nice and smooth. Next you will add the xanthan gum, salt and pepper and blend for another 5-10 seconds. You will see the sauce thicken up right before your eyes, it is actually quite amazing what xanthan gum can do. Pour your sauce over the cooked pasta and toss the chopped fresh oregano in along with it.
