Preheat the oven to 190C/Gas 5/fan oven 170C. Halve some of the pecans, leave some whole. Mix with peanuts, oats, sesame seeds, sunflower seeds and a pinch of salt in a large bowl. In a jug, measure the oil and pour into the mixture, then measure the honey – it will slide out easily. Stir together with a fork to break up any big clumps of oats.
