Prep
- Place roasted cauliflower in a large food processor and puree until smooth.
- Add in the remaining alfredo sauce ingredients, except for the pasta and mushrooms. Puree until smooth.
- Set aside the sauce while you cook the pasta.
- In a medium pot, cook the pasta according to the packaging instructions. Once the pasta is cooked to al dente, strain the pasta, reserving about ½ cup of pasta water. Place the pasta back into the pot, along with the reserved water.
- Add the Alfredo sauce to the pasta pot, and toss together with the mushrooms until evenly coated.
- Plate and top with vegan parmesan cheese, fresh sage, and extra pepper if needed.
