I just threw this together one day when we had some fresh-caught Skipjack Tuna steaks. That's the kind that goes into cans. It's so much better pre-canned. Skipjack tastes a bit stronger than other tuna, and though it's meaty like mahi or shark it's still a bit dainty in flavor so a light, bright sauce does well on it. Try grilling the tuna over actual charcoal or wood, with just a little light olive oil to keep from sticking. This also works really well on grilled pork loin.
