I grew up eating a lot of tuna belly in the Philippines because our area just has an abundance of seafood. I do not remember eating frozen seafood, especially fish for that matter! It’s kinda different here in Washington state, the “fresh” ones are so expensive and the frozen are not the best quality I’ve had. Oh well! That’s why I get so excited to go to the ocean because we always get fresh seafood, like tuna belly. The fishermen got it in the morning, and we cooked it for dinner the same day! It was so good:) When we got back home I just prepared the rest of our tuna belly because I didn’t want to freeze anything. I don’t mind having tuna belly for consecutive days if it is fresh and I don’t get to have it often. I marinade it in soy sauce (I used less sodium,1/2 cup), 4 or 5 tablespoon of olive oil, chopped garlic (3 cloves),then pepper. Marinated it for 4-5 hours. Then I grilled it for 4 minutes each side (medium heat). Enjoy with rice and dipping sauce (like vinegar or PINAKURAT is what I used;it’s a famous filipino vinegar.)
