Peele and boil 1 kg of sweet potatoes, then mash them. Mix with an entire egg that's been beaten, a pinch of grated cheese, salt, and pepper. Grease a baking dish and spread half the mashed sweet potatoes in it. In the center, add small pieces of yesterday's roasted meat, mixed with Minas cheese if desired, and some prosciutto. Top with the remaining mashed sweet potatoes, forming a dome shape. Drizzle with a little butter and bake.
