Preheat your oven to 200 degrees and line a large baking tray with baking paper.
Remove your Jus Roll pastry from the fridge 10 minutes before you want to make your palmiers, remove all packaging.
If using an egg, place in a bowl and beat lightly and put to one side.
Gently roll out your sheet and carefully spoon the Muhammara onto the puff pastry sheet, ensuring to spread it to each corner.
Now start by rolling the long side closest to you towards the middle of the sheet, make it as snug as possible.
Repeat on the opposite side until they meet in the middle. Lightly press together.
Using a sharp knife, cut into 1cm wide pieces and brush them with your beaten egg, or your plant-based milk for a vegan option.
Carefully place cut-side down onto your baking tray.
Pop into the oven for 18-20 minutes until golden brown.
Serve with the LEON Harissa Aioli Mayo.
