In a large wok or deep skillet, heat 1 tablespoon of vegetable oil over medium-high heat. Add the diced Chinese sausage or cured pork and cook until it releases its flavorful oils. Next, add the diced chicken and shrimp, and stir-fry until they are fully cooked and lightly browned. Remove the meats and set them aside.
In the same wok, add the remaining tablespoon of vegetable oil. Stir-fry the diced carrots and frozen peas until they become tender. Be sure to keep the vegetables crisp and vibrant by cooking them quickly over high heat.
Push the vegetables to one side of the wok and pour the lightly beaten eggs into the empty space. Allow the eggs to cook for a moment until they start to set, and then gently scramble them. Once the eggs are fully cooked, mix them together with the vegetables.
Add the cooled cooked rice to the wok, breaking up any clumps as you stir-fry. The rice should absorb the flavors of the meats, vegetables, and eggs, creating a harmonious blend of tastes.
Pour the prepared seasoning mixture over the rice and toss everything together to ensure the rice is evenly coated with the flavorful sauce.
Return the cooked chicken, shrimp, and diced bell peppers to the wok. Stir everything together, ensuring that all the ingredients are well distributed throughout the rice.
Taste the Yangzhou fried rice and adjust the seasonings to your preference. If needed, add a pinch of salt or a little more soy sauce to enhance the flavors.
