Place the oil from the tuna cans in a wok or large pan. Add the onion and garlic and sauté' until translucent. Add the tuna and sauté' until the liquid evaporates and the tuna turns crispier.

Add the red chili, soy sauce, and liquid seasoning and continue cooking for another 3 minutes. At this point, you can turn off the flame and mix in your mayonnaise. You can serve it this way by adding your toppings or proceed to step 3.

For plating, melt your margarine or butter to a sizzing plate. Add the tuna sisig mixture and place your topping. (optional, you may add one egg on top if desired). Share and Enjoy.
