Lay the flatbread on your work surface. Use a butter knife to distribute the chocolate hazelnut spread in a thin layer. It won't cover the entire surface of the flatbread.

Add the nut butter and spread it so that covers the surface of the flatbread.

Peel the banana and set it along the shorter edge of the flatbread.

Roll it up inside the flatbread so it is in the center.

Use a serrated edge knife and cut crosswise in half (younger kids will need a parent to help with this).
