Greek Bifteki with Feta Filling

Cut the feta into 6 strips, about 5 cm long.

Finely chop the red onion, fresh mint, parsley, and oregano. Soak the toast in a bowl with 50 ml of water. Add the chopped herbs, onions, a pinch of pepper, 1 tsp salt, the lemon zest, the egg, and the minced beef, and mix everything thoroughly to form a uniform mass.

Divide the meat mixture into 6 equal portions. Form each portion into an oval patty, place a piece of feta in the center, and firmly enclose the cheese with the meat to form elongated patties (bifteki).
