Place all the ingredients for the sauce mix in a small bowl and whisk together until it’s well combined.
Add the butter into a large non-stick wok or frypan and heat over medium-high heat until melted. Add the eggs. Cook and scramble constantly until the eggs are mostly cooked.
Add the rice onto the egg. Cook and chop the rice with your spatula, to separate the grains and coat the rice with egg. Cook until the rice is heated through.
Pour the soy sauce mixture evenly over the rice. Cook and stir constantly, until the sauce mixture has evenly coated the rice.
Add the green onion and stir to mix well. Taste the rice and season lightly with sea salt if needed. Stir and mix thoroughly, so the salt is evenly dispersed.
Transfer the rice to a bowl and serve hot, topped with some BBQ prawns for a hearty meal.
