Preheat your grill and your cast iron pan.

In a bowl mix together lime zest, juice, honey and chili powder. This is your marinade - set aside.

Season salmon with salt and pepper.

Pour and swirl around 1 tbsp of olive oil into hot cast iron pan.

Place salmon in pan flesh side down. Sear for 1-2 minutes or until starting to get a nice brown.

Spray skin with cooking oil. Flip salmon over to skin side down.

Baste with marinade and do so at least 1-2 more times while salmon is cooking.

Close lid and cook salmon 6-10 minutes or until skin flakes easily with a fork.

Remover from pan and serve.
