Drain cashews well. Combine all ingredients in a powerful blender and blend until completely smooth and creamy, scraping down sides as necessary. This may take a few minutes, be patient. Transfer mixture to a bowl and refrigerate until chilled, about 2 hours. (Keeps for several days in refrigerator.)
To serve, spoon cashew yogurt into bowls and top with blueberries, mango slices, and lime zest.
