Preheat the oven to 375°F (190°C).

Grate the rusks.

Mix the ground beef, eggs, grated rusks, vinegar, and spices.

Lay plastic wrap on the counter, centered, with extra on both sides.

Place the beef mixture on it.

Cover again with plastic wrap. (Essentially, make a 'sandwich' with the beef between the plastic wrap.)

Roll out into a thin 'sheet' using a rolling pin.

Use a large cup as a cutter to cut out 9 large burgers.

👉 They will shrink and puff up a bit when baking.

Line a baking sheet with parchment paper and oil it.

Place the burgers on it.

With the remaining beef, form 4 meatballs.

Bake for exactly 20 minutes.

Remove from the oven and turn it off.

If you want to add cheese, do it now, and return to the turned-off oven for 1-2 minutes until it melts.
