Parmesan Mashed Potatoes
10 medium potato(es), red (about 2 1/2 lbs) 1/2 cup buttermilk, warmed (for buttermilk substitutes you can always add 1 tablespoon of vinegar or lemon juice to 1 cup milk and let sit for 5 minutes- so in this case you'd add 1/2 a tablespoon to 1/2 cup milk) 1/2 oz SOY Parmesan cheese, grated (about 3 tablespoons) 1/4 cup chives, chopped 1 tsp table salt 1/8 tsp black pepper, ground
Place potatoes in a large pot and cover with an inch of water; bring to a boil, reduce heat, simmer and cook until fork-tender, about 30 minutes. Drain and return potatoes to pot.
Mash potatoes with a potato masher. Stir in remaining ingredients and mix well to combine. Yields about 2/3 cup per serving.
