Preheat your griddle or skillet to medium-high or high heat, and place about a tablespoon of oil down.
Dump on the onions and pork, and stir fry for about 2 minutes
Add in the frozen peas and carrots and stir fry until heated through and the edges get a little crispy.
Move the pork and the vegetables over to the side of the griddle that is NOT a hot spot or remove it from the skillet.
Put down some more oil on the griddle / skillet, and let it heat up.
Add on the cold rice and break it apart with your spatula. Continue moving it around evenly coating with oil and letting it get toasty. Add more oil as needed.
Combine the meat, vegetables, and rice together and stir and toss until they are evenly combined.
Drizzle the soy sauce and sesame oil on top and continue to stir and cook until it is evenly distributed.
Make a hole in the middle of the rice and add a little more oil.
Crack the eggs inside, stir with the spatula, and toss to combine with the rice.
