Use a mortar and pestle to pound the garlic, bird's eye chilies and salt to a rough paste. You can also use an electric chopper. Set aside.
Heat oil in a pan. Add the onion and cook for 30 seconds. Then add the garlic chili paste and cook for 2-3 minutes.
Add the chicken and stir-fry for 3-4 minutes or until the chicken is cooked.
Add the rice and stir fry for a minute or 2.
Stir in oyster sauce, fish sauce and light soy sauce.
Stir-fry until well combined and the rice is evenly colored. Season with more salt if required.
Toss through the holy basil and remove from the heat.
Serve with a sunny-side up.
