Wash and pat dry the basil leaves. Set aside.
Add the roasted macadamia nuts to the mini food processor. Process 10-20 seconds until the macadamia nuts are chopped into smaller pieces.
Then add the basil, grated parmesan cheese, garlic, sea salt, and half the olive oil.
Process until all the ingredients are well mixed and there are no big pieces of macadamia nuts or basil.Note: You may have to process for about 10-20 seconds, then use a small spatula to mix things up a bit. And then process again. Add the rest of the olive oil and process again for another 10-20 seconds. If you prefer a more "loose" pesto, feel free to add more olive oil. Then it's all done and ready to eat ^_^
