Begin by cracking the eggs into a large, shallow baking dish and whisking them.

Dip the rice paper sheets into the eggs—use three sheets—and lay them side by side on a flat surface, slightly overlapping.

Finely chop the onion and sauté it with the ground beef in a hot pan with a little oil.

Spread the cooked beef mixture over the rice paper sheets, then add the sautéed spinach and crumbled feta cheese on top.

Carefully roll everything up and shape it into a spiral.

Sprinkle sesame seeds over the top and bake in the oven for 15 minutes at 200°C (392°F).
