Traditional Roast Beef Hash
2 cups roughly chopped cooked roast beef or pot roast beef
1 large Russett or 2 smaller Yukon gold potatoes, peeled and quartered
1 large onion, peeled and quartered
3 tablespoons extra virgin olive oil
Salt and pepper
Take approximately equal proportions of beef, potatoes, and onions and put them through a meat grinder using a medium grinder attachment so that they are well mixed and ground.
If you don't have a meat grinder, you can pulse a few times in a food processor, or finely chop by hand.
Heat the olive oil in a large frying pan, preferably a cast iron pan, on medium high to high heat. Add the hash to the frying pan so that a half an inch of hash covers the bottom of the pan. If you have more hash to cook, do so in separate batches. Brown the hash, stirring only infrequently at first to make sure that the hash has an opportunity to brown well. As you cook the hash, add pinches of salt and fresh ground pepper. Do this a couple of times with each batch of hash. Cook for at least 10 minutes and until the hash is well browned. Serve immediately with ketchup.
