This recipe is cooked over hot coals on an outdoor grill but you can use a regular grill or grill pan if you prefer. Toss some veggies on the grill, too, to complete your meal. It's important not to marinate the fish for longer than two hours or the acid from the lime juice can make the tuna taste mealy. Tuna is often sold in chunks, rather than steaks, at a considerably lower per-pound price. Threaded on skewers and grilled as kebabs, they can look very nice. Consider that as an alternative to serving tuna steaks when you want to save a few dollars.
