In a mixing bowl, combine the flour and salt.

Make a well in the center, add the egg, vegetable oil, and water. Mix until a dough forms, adjusting water if necessary.

Knead the dough on a floured surface for about 5 minutes until smooth.

Cover the dough with a cloth and let it rest for at least 20 minutes.

In a skillet, sauté the onion and garlic until translucent, then add the ground meat. Season and cook until browned.

Roll out the dough to about 1/8 inch thickness on a floured surface.

Cut circles about 3 inches in diameter, place filling in the center, fold over, and seal edges.

Bring a large pot of salted water to a boil. Cook pierogi in batches for about 3-4 minutes, or until they float.
