Prohoroff’s Piroshki

Add the ground beef to the slow cooker. Top with the salt, pepper and garlic powder. On top of that, place the finely chopped onion.

Cube the butter over the onions. Cover and slow cook on low for 5 to 6 hours until onions are soft and sweet. Smash the beef and onions together and add the Worcestershire sauce and tomato paste, then stir.

In the meantime, you’ll have defrosted the frozen puff pastry sheet. Roll it out until it’s twice its size (using flour so the dough doesn’t stick). Cut the sheet into 6 equal pieces, which should be about 5 inches by 5 inches each.

One at a time, place a small sheet of pastry on an oiled baking sheet. Spoon in about 1/4 cup of the beef and onion mixture, then fold the sheet, corner to corner, twice and pinch for closure.

Cook at 400ºF for 15 minutes, or until golden and flaky.

Serve while hot.
