This #dish is #simple to prepare but magically delicious in the end! First, we boil the potatoes, then #mash them in a #baking dish. On top of the potatoes, we layer savory #ham tender onion, and generously sprinkle cheese. Then, we pop it into the oven, preheated to 180 degrees Celsius, and bake until golden brown. Simple, hearty, tasty! Serve hot and enjoy every bite of this unparalleled treat.
