In a pot, add water and chicken. Boil over high heat, about 10 minutes or until chicken is cooked. Drain the chicken and let it cool down. When the chicken has cooled down, shred using your clean hands or a food processor.
Using a skillet over medium-high heat, add oil. When oil is hot enough, add garlic and cook until light golden brown. Add chopped onions and cook until translucent.
Add the shredded chicken and soy sauce (you add more later on if you like). Mix it so the chicken absorbs the soy sauce. Cover the skillet for 5 minutes. Remove the cover and mix again. This time, if you’d like to add oil, you can add it or maybe soy sauce. The oil is added so the chicken doesn’t get too dry. Cover the skillet again and check if you like the taste and texture. For me, I like it on the toasted side so I cook it longer and just check the chicken from time to time to avoid burning it. (Please watch the video for visuals. It is in Tagalog, but it is shown there the color and texture.)
