Preheat your oven to 375˚F (190˚C) and line two baking sheets with parchment paper.

In a large mixing bowl, combine the imitation crab meat, cream cheese, mozzarella cheese, garlic, and green onions. Add soy sauce and sugar, then mix until well blended.

On a lightly floured surface, roll out the puff pastry to smooth it out into a rectangle shape.

Spread the filling evenly across the puff pastry, leaving a ¼-inch border.

Roll the pastry tightly from one edge to form a log. Wrap in plastic wrap and refrigerate for 15–30 minutes.

Slice the log into ½-inch thick pinwheels.

Arrange the pinwheels on the baking sheets, brushing the tops with the whisked egg.

Bake for 15–20 minutes, rotating halfway through, until golden and flaky.

Let them cool slightly before serving warm with your favorite dipping sauces.
