In a large wok or saucepan on medium to high heat place 2 tablespoons of vegetable oil and heat. Stir fry the chicken breast for 2 to 3 minutes, and then add the prawns. Cook for another 1-2 minutes, or until the prawns have changed color and the chicken is cooked.
Move the prawns and chicken to the side of the pan and add the eggs. Make the eggs into a thin omelette. When the eggs are almost cooked, gently break it up into smaller pieces. Remove prawns, chicken and eggs from pan and set aside for later.
Place the remaining 2 tablespoons of oil in the heated pan and add garlic and onion. Sauté the garlic and onion until the onion turns light brown. Then add the carrot, green peas, and capsicum. Cook for 1 to 2 minutes.
Add the soy sauce, curry powder, black pepper powder, turmeric, coriander (cilantro) powder, dried chili flakes, sugar, chicken powder stock, and sesame oil. Mix well and cook for a few seconds.
Add the cooked rice to the pan, as well as the prawns, chicken, and spring onions. Mix the ingredients together until well combined. Cook for another 3 to 4 minutes.
Turn off heat. Season with salt and pepper to your liking.
