Heat oil in a heavy pan over medium high heat. Add garlic; sauté for 1 minute or until lightly brown.
Add brown sugar; sauté for 30 seconds. Add pork pieces; cook for 3 minutes or until meats are no longer pink.
Add soy sauce; stir and cook for 1 minute and then add water. Bring to a boil. Reduce heat, cover and let simmer for 1 hour or until pork is tender. Add more water as needed. (I added ½ cup water each time mixture runs out of sauce)
Add oyster sauce and hard boiled eggs and gently stir. Adjust seasonings and simmer for 1 more minute. Transfer to a plate.
Serve with steamed rice. Enjoy!
