Heat oven to 180C/160C fan/gas 4. Toss together the oats, mixed seeds, peanuts, chickpeas (after draining them and patting them dry) in an oven tray along with the chilli flakes, turmeric, ground cumin, crushed coriander seeds and flaked sea salt. Stir through the rapeseed oil. Bake for 25-30 mins or until lightly golden and crunchy, stirring halfway. Leave to cool completely before storing (see below). Sprinkle over salads and soups.
