Step 1: Cook the Fried Rice

1. Heat a large pan or skillet over medium heat and add butter or oil.
2. Sauté the chopped onions until they become soft and translucent, about 2-3 minutes.
3. Add the chicken (or shrimp/tofu) and mixed vegetables to the pan, stirring for another 2 minutes until they are heated through.
4. Add the cooked rice, breaking up any clumps with a spatula. Stir well to combine with the other ingredients.
5. Pour in ketchup, soy sauce, and Worcestershire sauce, mixing thoroughly until the rice is evenly coated and has a reddish hue. Cook for another 2-3 minutes.
6. Once done, transfer the fried rice to a plate and shape it into a mound using a spoon or bowl for a neater presentation.

Step 2: Make the Omelet

1. In a bowl, whisk together eggs, milk, salt, and pepper until well combined.
2. Heat a non-stick pan over medium-low heat and add butter or oil.
3. Pour the egg mixture into the pan, swirling to create a thin, even layer.
4. Cook gently, stirring slightly to create a soft, custardy texture while keeping the shape intact.
5. Once the omelet is mostly set but still slightly soft in the center, carefully slide it over the fried rice mound.

Step 3: Serve and Garnish

1. Use a paper towel or spatula to tuck the edges of the omelet under the rice, shaping it neatly.
2. Drizzle ketchup over the top in zigzag patterns or write a cute message if serving for kids.
3. Garnish with chopped parsley or an extra drizzle of Worcestershire sauce for extra flavor.
4. Serve immediately while warm.
