Add cauliflower and potatoes and simmer until tender (about 15 minutes).
Drain the water and transfer the cauliflower and potatoes to a food processor or blender. Add vegan butter and garlic power and blend until desire texture is formed. For a smoother texture, add a tablespoon or two of non-dairy milk.
Season with salt and pepper. Enjoy over stuffing muffins (see below).
