Heat 2 Tbsp oil in a large non-stick skillet on med-high heat. When it’s hot, add in the shrimp, season with S&P. Allow to cook for about 1 minute, flip and cook another minute until cooked through. Remove to a plate and set aside.
Add another drizzle of oil, if needed, and add in the chicken. Season with S&P and cook, stirring occasionally, until browned and cooked through. Remove to a plate and set aside.
Turn the heat down to med-low. Add a drizzle of sesame oil to the skillet. Pour in the eggs and allow to cook, undisturbed, until almost set. Flip and cook another minute. Slide onto a board and slice into ribbons.
Turn the heat back up, add in another drizzle of oil and the onion. Cook until slightly softened.
Add the rice to the skillet, spread into an even layer and leave to cook, undisturbed for 2-3 minutes. Stir and leave to cook another 2-3 minutes until the rice is browned and crisp in spots.
Add in the soy sauce, remaining sesame oil, butter, peas and a pinch of salt. Mix well.
Add the shrimp, egg and chicken back into the pan and stir.
Top with the green onions and serve.
