good olive oil = EV
(IMO)

Our local bakery has a great Taragon Chicken Salad that I’ve yet to duplicate!

"good olive oil = EV (IMO)"

I quite agree. However in this preparation, the flavor of a good (the only kind I use!) EV olive oil can be a bit strong for this dish.
I like to use EV when it can be appreciated for what it brings. In this, with the hard-boiled eggs and the 'lighter' fare, it can quickly turn a bit 'musty' and strong in the mix.
(yeah...thats personal experience speaking...lol..cook, eat and learn!))
