Well, Sharon* got some Tuna steaks on sale at at the grocery store, and we cooked them. It was dead nuts simple, I dusted it with my curry spice rub, let it sit for about 10 minutes for the spices to mingle, and then seared each side for about 5 minutes in a hot pan with a bit of olive oil, and served.
There was just a bit of pink in the middle, and it turned out very nicely.
