Place wok or pan over medium low heat. Add the Chinese sausages and stir fry for about 1 minute to render its fat, then set them aside.
Turn the fire up to medium-high. Using the same cooking vessel, add the diced onions and white parts of the scallions, then stir for about 20 seconds. Spread 1 tbsp of oil on the pan, then add the frozen peas and garlic and cook for another 45 seconds to 1 minute or until the vegetables begin to wilt.
Add the refrigerated rice. Using the edge and surface of a spatula, break up the rice while stir frying for about 1 min.
Create a well in the center of all the ingredients, then spread 1 tbsp of oil in the well. Crack 2 eggs into the well and immediately stir to break up the yolks, then fold the rice in while stir-frying so that the eggs click onto each grain of rice.
Add fish sauce, soy sauce, sesame oil, sugar, salt and white pepper powder, then stir until ingredients are well-incorporated and cooked. Taste the rice and adjust to suit your preferences.
Add the Chinese sausages back into the pan, then give the rice a brief stir and serve!
