In a food processor, add the cashews and almonds and process into crumbs. Add the dates and salt. Process again to form the base and press this mixture into a lined cake tin (preferably with a removable base for easy removal. @mindful_moose used a 22cm tart tin).
Drain and rinse the cashews well. Add them into a high-powered blender or food processor, along with the remaining ingredients. Blend until completely smooth. Pour into the base and smooth out the top. Place in the freezer to set for a couple of hours, or just leave it in the fridge overnight. Top with sliced kiwifruit and coconut.
