Heat 1/2 tablespoon of butter in a large skillet over medium-high heat until melted. Add egg, and cook until scrambled, stirring occasionally. Remove egg, and transfer to a separate plate. Scrape down and rinse the pan, if needed.

Return pan to heat. Add an additional 1 tablespoon butter to the pan and heat until melted. Add carrots, onion, peas and garlic, and season with a generous pinch of salt and pepper. Saute for about 5 minutes or until the onion and carrots are soft. Increase heat to high, add in the remaining 1 1/2 tablespoons of butter, and stir until melted. Immediately add the rice, green onions, soy sauce and oyster sauce (if using), and stir until combined. Continue stirring for an additional 3 minutes to fry the rice. Then add in the chicken and eggs, and stir to combine. Add the sesame oil and sriracha, and stir to combine. Remove from heat.

Serve warm.
