2 (24-oz.) packages refrigerated mashed potatoes (we tested with Bob Evans)*
4 ounces blue cheese, crumbled
1/4 cup butter, cut into pieces
1/4 teaspoon salt
1/4 teaspoon freshly ground black pepper
Heat potatoes in a large saucepan over medium heat, stirring often, 6 to 8 minutes. Add blue cheese, butter, salt, and pepper, stirring just until butter is melted.
*Look for this brand of mashed potatoes in the meat department of your grocery store.
