Thaw the puff pastry slices according to package instructions.
In a pan, braise the onion cubes with olive oil and let cool.
Puree the soaked cashew nuts together with garlic, lemon juice, yeast flakes and, if necessary, add some water in a blender. Season the “cheese” dip mixture with salt and pepper.

Brush each strip with half a teaspoon of onion cubes and half a teaspoon of “cheese” dip and twist together at the ends.
