This yummy mashed potato recipe makes a little over 6 cups. And each cup is just 70 calories. I like to add in two garlic cloves to this vegan mashed potato recipe. I pop them in the water with the potatoes and they soften up. Then I mash them in with the potatoes for a perfect garlic mashed potato recipe. You can choose to remove them all together, pull them out before mashing, or adding more for a stronger flavor.
