Peel the potatoes and chop into small cubes. (Smaller pieces cook faster).
Place the potatoes in a pot and cover with water. Add salt. Bring to a boil. Cook until potatoes are soft, about 20 minutes.
Drain potatoes and set aside.
On the stovetop or in the microwave, heat the non-dairy milk and Earth Balance Spread until the vegan butter is melted. Do not boil.
Use a fork or a potato masher to press the potatoes until smooth. Combine the vegan milk and butter mixture with the potatoes. Add salt and pepper to taste.
