Prep your rice: Use cold, day-old rice for the best texture. Break up any clumps with a fork.
Cook the aromatics: In a large pan or wok, heat oil and butter. Sauté garlic and onion until fragrant.
Add proteins: Stir in Chinese sausage and shrimp. Cook until shrimp is opaque and sausage is slightly crispy. (Can use tofu for a vegetarian version)
Scramble eggs: Push ingredients to one side. Add beaten eggs and scramble until just set.
Add rice & veggies: Toss in rice and frozen vegetables. Stir-fry everything together.
Season: Add fish sauce, oyster sauce, soy sauce, sugar, and pepper. Stir well to coat.
Finish & serve: Garnish with scallions and cilantro. Serve hot with chili sauce or pickled veggies. Add more fish sauce, soy sauce or salt for taste.
