Besides how heavenly it tastes, the other thing I love about pesto is that it can be whatever you want it to be. Traditional Italian pesto is, of course, made strictly with basil, pine nuts, Parmesan, garlic, and really good olive oil. It's a classic sauce, no contest.

As with pistou, the term pesto has come to mean many things across the world.
