Just mash potatoes plain with butter or you can add yummy ingredients like cooked bacon, cheese, parsley, green onion, garlic, etc. Stuff into a greased muffin tin, run a fork along the top and brush with melted butter or olive oil. Bake at 375 degrees or until tops are crispy and golden.
Also remember there are varying sizes in muffin pans so you can choose the serving size!! Using mini muffin tins you can turn this into a healthy alternative to chips or wedges too. You still get the soft potato centre with the crunch on the outside without all the fat!
