You can substitute 2/3 cup; 1/3-less-fat cream cheese, 2 tablespoons fresh chives, and 1 tablespoon chopped onion for the flavored cream cheese.
3 pounds peeled Yukon gold potatoes, quartered
2/3 cup fat-free milk
1 teaspoon salt
2/3 cup (5 ounces) light cream cheese with chives and onions
How to Make It
Place potatoes in a Dutch oven, and cover with water; bring to a boil. Reduce heat, and simmer for 10 minutes or until tender. Drain. Return potatoes to pan; add the milk and salt. Mash the potato mixture with a potato masher to desired consistency. Add the cheese, and stir just until blended.
