It's Olive Oil for God's sakes.
Better to put it on the chicken then on the pan, you only need a very small amount.
If you're overly paranoid get a non-stick pan or seasoned cast iron pan and use nothing, once the chicken is seared enough on the first side you will be able to flip it with ease.
Healthy Fat is not the enemy.
If you MUST use a spray product don't use PAM (chemicals) use an Olive oil spray.
