Preheat the oven to 175°C fan.
Heat a shallow pan to medium, add the sesame seeds. Heat and stir until golden, add the pumpkin and sunflower seeds, stir and remove from the heat. Now add the honey, salt, zest and oil, stir. Spread the mixture with a spatular or palette knife on a parchment lined baking tray as best as you can and as thinly as possible.
Bake 5-10 mins, or until golden. Remove from the oven. As the thins cool, they begin to harden, cut into even size pieces if that’s what you like or cut into shards.
Store in an air-tight container for up to 2 weeks. They will soften and become more chewy over time but are still good to eat.
