Preheat the oven to 325°F and line a baking sheet with parchment paper.
Spread the oats and macadamia nuts on the baking sheet, mixing them to combine, and bake them for 10 minutes, stirring occasionally, until lightly browned. Transfer the toasted oats and macadamia nuts to a large bowl then stir in the flaked coconut.
In a separate medium bowl, whisk together the honey, vegetable oil, egg whites and vanilla extract. Pour the mixture over the oats and stir until combined.
Pour the mixture back onto the lined baking sheet, spreading it into an even layer, and bake it for 30 to 40 minutes, stirring every 10 minutes, until it’s golden brown. Remove the granola from the oven, stir it one more time then allow it to cool completely on the baking sheet.
Once the granola has cooled, stir in the dried pineapple and serve it immediately or transfer it to an airtight container and store it for up to 2 weeks at room temperature.
