Tuna Bistek with Eggplant

Tuna Bistek with Eggplant. During my recent trip to Sarangani, I brought back with me one box full of assorted cut of Tuna. Sarangani is the Tuna capital of the Philippines. I have to get the Styrofoam box filled up to maximize the space and of course to take advantage of the cheaper price of Tuna from the source. Now run out of what to do with the rest of Tuna Kinilaw cuts that I had.
