Add the cauliflower and potatoes to a pressure cooker or steamer with 1 cup of water. Cover or cook on high pressure for 10 minutes, then carefully release the pressure and drain.
While the vegetables are cooking, prepare the fettuccine according to the package instructions. Drain and set aside.
Heat a large skillet over medium heat. Add the onion and garlic with a splash of water and sauté for 3–4 minutes, until softened.
Add the mushrooms and cook for another 3–4 minutes. Stir in the broccoli and peas, then continue cooking until the broccoli is tender-crisp, about 5 minutes.
Transfer the cooked cauliflower and potatoes to a high-speed blender. Add the nutritional yeast, miso paste, plant-based milk, soaked cashews (or cashew butter), garlic powder, and black pepper. Blend until completely smooth and creamy.
Pour the Alfredo sauce into the skillet with the vegetables and stir to combine.
Add the cooked fettuccine and toss until evenly coated. Cook for 3–5 minutes, allowing the sauce to thicken slightly and cling to the pasta.
Season with additional black pepper to taste. Serve warm and enjoy.
