Here is the best way by 100% to eat tuna. First go get 3 to 5 lbs of sashimi grade ahi. It has to be less than 12 to 18 hours old. If you are lucky enough to know the owner of one of the largest fisheries in Hawaii that helps cause you can walk in and get it free when you want (as long as they have it available). hehe that was my way of bragging cause it costs a shitload of money and I would buy sometimes. Anyway, bring it home and rub some olive oil on it and then throw it on the grill and cook for about 30 to 40 laps in the pool. Doesn't take long. And yes you will have to turn it on all four sides. Now take it to the kitchen and put it in the fridge to get cool. Once cool take out and bust it up in a large bowl with your hands into small pieces. Now mix in low fat mayonaise, dijon mustard, lemon pepper, garlic salt, ground course black pepper, some sweet relish, handful of capers and thats it. Mix it up. You will have the best tasting tuna you will ever taste. You can add just about anything you want. I usually just added what I had in the cupboard. The important stuff is the mayo and mustard. Sometimes I would just add that and some pepper and salt. I would put the bowl in the fridge and eat when I was hungry. Made sandwiches or just out of the bowl. Generally lasted 2 to 3 days.
