Garlic Mashed Potatoes with Sour Cream and Chives

Mashed potatoes are easy to make in the slow cooker—and convenient, too, since you can cook and serve them in the same container. They also hold well on the Keep Warm setting if they finish cooking before the rest of the meal. The addition of sour cream and chives adds an extra flavor boost, but you can omit them (as well as the garlic) for more basic mashers. For soy-free, use soy-free vegan butter, vegan sour cream, and nondairy milk.
