Recently had some blackened mahi when I was in Florida and wanted to give some tuna the blackened treatment ( mainly because it was on sale :)
). Seasoned it with lime juice and Smokin' Guns Hot BBQ rub. I let the egg get up to 500 and threw it on. Seared it on all sides till it was medium rare. I remembered to take pictures of my cook this time so I could actually post something. It turned out really well and I plan on doing it again. I had some Bone Suckin' Sauce on the side but it was unnecessary.
I had coucous & spinach with it but turned out pretty bland. Maybe I should do it on the Egg next time :)
