Add half of the butter to a heated pan. Crack and beat the eggs well. Then, add them to the pan and stir-fry them. Once cooked, set the eggs aside.
Add the rest of the butter to the pan. Add the minced garlic and fry them until fragrant. Add the Chinese sausages and stir-fry them for 3 to 5 minutes.
Add the carrots and peas. Cook them with the sausages for 5 minutes over medium heat, stirring frequently.
Add the rice and break it up using a wooden spoon or spatula.
When the rice grains are separated, season them with fish sauce, soy sauce, chili sauce, and ketchup. Stir well.
Then, stir in the eggs and cook for another 2 to 3 minutes.
Turn off the heat and scoop the rice onto serving plates or bowls. Enjoy!
