An easy side dish with great flavor. I love the goat cheese in this! If you want to make these ahead, chill them and reheat before serving, adding some extra liquid. Stir in the chives right before serving.
Place potatoes in a saucepan, and cover with cold water to 2 inches above. Add 1/4 teaspoon salt; bring to a boil. Reduce heat, and simmer 15 minutes or until potatoes are tender; drain. Return the potatoes to pan over low heat; add remaining 1 teaspoon salt and butter to pan. Mash the potatoes with a potato masher to desired consistency.
Add cheese and peper to potato mixture; stir until cheese melts. Stir in milk; cook 1 minute or until thoroughly heated, stirring frequently. Remove from heat; stir in chives.
