Set the pan on the stove again at medium-high heat and add the spaghetti. Sauté lightly for a few minutes. Move to one side of the pan, lower the temperature and add olive oil, garlic and ground red pepper. Stir constantly until the garlic becomes aromatic, about 30 seconds. Place in a bowl to serve and add almond flour. Mix again to combine well. Serve immediately with fresh parsley and vegan or regular cheese. The cheese is optional.
