Method
Blitz the pistachios in a food processor until you have rough crumbs.
Preheat the oven to 150°C/300°F/Gas mark 2 and line a baking sheet with non-stick baking parchment. Make the granola by combining the oats, walnuts, wheatgerm, olive oil, honey and cinnamon in a large bowl, tossing to coat evenly.
In a separate bowl, whisk the egg white until white and frothy. Stir into the granola mixture, distributing it evenly throughout.
Spread the mixture in a single layer on the lined baking sheet.
Bake in the oven for 50 minutes. About halfway through the cooking time, use a large spatula to turn over sections of the granola carefully.
When it is evenly browned and feels dry to the touch, transfer to a cooling rack. Allow to cool completely before breaking up into clusters.
Stir the lime zest into the soya yoghurt.
Place a layer of granola clusters in the bottom of four glasses or bowls. Top with a generous tablespoon of the lime yoghurt and a generous amount of chopped pistachios. Repeat this layering process and serve immediately.
