Place mayo, parmesan cheese, garlic powder and freshly cracked pepper in a small bowl.
Mix well.
Store in an airtight container in the refrigerator for up to 2 weeks.
Notes
If you don't have garlic powder, you can substitute onion powder. It works just as well. Play around with the spices and find your favorite combination.
