Place macadamia nuts in blender cup; pulse just until nuts have broken down into a meal-like consistency. Don't overprocess because you'll process again with the rest of the ingredients.
Add in fresh basil, parmesan, oil, minced garlic, and salt; pulse until ingredients have combined and no big pieces of basil remain.
Transfer to 8oz jar and store in fridge, about 2 weeks.
Use on pasta, pizza, sandwiches and more!
Notes
Some of my favorite jars to use for storing are weck jars.
