Directions
Prepare the Ingredients:
Ensure all ingredients are prepped—boil the potatoes, carrots, and eggs in advance and let them cool before grating or chopping.

Assemble the Roll:

Lay the lavash bread flat on a clean surface.
Spread a thin, even layer of mayonnaise over the bread.
Layer the Ingredients:

Begin with the grated potatoes, spreading them evenly over the lavash.
Add the grated carrots, followed by the chopped eggs and red onion.
Scatter the diced herring evenly across the surface.
Roll It Up:

Carefully roll the lavash tightly, ensuring the filling stays in place.
Wrap the roll in plastic wrap and refrigerate for at least 1 hour to firm up.
