Mashed potatoes don’t have to be heavy to be comforting. In this version, I take classic potatoes and give them a Greek, savory-tzatziki twist: whipped cottage cheese for creaminess and protein, Greek yogurt, grated cucumber, dill, lemon, garlic, and a finish of olive oil. The result is a mash that’s fresh, bright, and very Mediterranean — but still cozy enough to sit next to a roast or holiday main. It’s a great make-ahead side and a smart way to work more Greek flavors into everyday meals.
