One of my favorites: dice onion into a heated skillet (nonstick)with a bit of cooking oil. Cut cold potatoes in their container and dump over the onion. As onion begins softe& potatoes warm, start mixing the two ingredients with spatula. Add black pepper and salt. Allow mixture to lightly brown, then turn them. Do this until the onion is very soft and there are crispy areas throughout. You may also add diced bell pepper at the start.

When I make Shephard's Pie, it's to use all leftovers. I add leftover meat, vegetables and gravy if I have it. I bake it in a pie pan. For pierogis, I use packaged wonton wrappers and add cheese, chopped onion, minced garlic and/or sauerkraut to the potatoes.
