Costco just brought back the Loaded Mashed Potatoes at the deli and these are a holiday must-have. Creamy, cheesy, and packed with flavor, they’re the easiest heat-and-serve side for gatherings or weeknight dinners. A fan-favorite return—share this with someone who loves Costco comfort food. #costcofinds #costcowonders #costcoinfluencer #costco #costcodeli #comfortfood #holidaydinners #costcobuys #costcodeals | Costco Wonders
