Method

This snack will need to be prepared at home in advance but will keep for days - ideal for long adventures.

Pour soy sauce into a bowl and stir in sunflower seeds. Allow to marinade for 10-15 minutes.

Drain the mixture through a sieve (you can reuse the leftover soy sauce) and spread the sunflower seeds evenly on a baking tray.

Use another baking ray for the pumpkin seeds.

Pre-heat oven to 190C or Gas Mark 5 and roast the sunflower seeds for about 16 minutes. Roast the pumpkin seeds for 8 minutes.

Using a spatula, scrape the seeds off each tray into an airtight container. Secure the lid and shake to mix well.
