Heat the oil in the pot. Then add the meat with the 2 cloves of garlic (whole, don't cut them) as well as the onion (whole as well).

Season with salt and pepper and let it simmer for about 20 minutes (don't add any water yet because the meat will let out its juices).

Boil some water and add it to the pot so that it covers the ingredients.

Allow it to cook over relatively slow heat for an additional 1 1/2 hour.

Five minutes before you turn off the heat add the oregano and the juice of the 2 lemons. Ready!!!
