Here's 2 of my favorites for both salmon and tuna: 1. - Marinate tuna steaks in lime juice, olive oil, salt & pepper. Grill (8-10 min) after a couple hours - serve with roasted red peppers, eggplant and garlic 2. -marinate steak in lime and grated lime rind. Grill (5-8 min) -serve with mango/papaya chutney --chop up 1 papaya and 1 mango (you might be able to get these canned) --dice a fresh chili (do NOT stick your fingers in your eyes after handling the chili seeds - I learned that the hard way :). Leave the seeds in if you want it to be hot and spicy. Otherwise, save them for some other dish. --chop up about 3T fresh cilantro --mix it all up and season with salt and black pepper to taste.
