Homestyle potatoes. Peel (or not) and slice 1/4" thick. Chop up an onion. Dump a hot skillet with several tablespoons of oil-bacon grease is better. Cut heat to medium low, cover and let cook until potatoes are soft. Take the cover off, turn up the heat and brown, turn over and brown. I usually flip it quite a few times to get that browned look and flavor. Cover with shredded sharp cheddar cheese, cut off the heat and cover. Serve cut into wedges after the cheese melts. I like to sprinkle a little soy sauce on it too.
Since cast iron is such a good conductor, you can use it to that meat too. Lay the frozen meat in the skillet and leave it alone. If in a hurry, remove the meat and heat the skillet under running hot water. Turn the meat over.
