Break up 4 cups cold, day-old cooked white rice with clean hands or a fork so there are no large clumps. Beat 4 large eggs in a small bowl and set aside.
Heat a large wok or 12-inch skillet over high heat. Once the pan is very hot, add 2 tablespoons neutral oil and swirl to coat.
Add 4 minced garlic cloves, 1½ teaspoons grated fresh ginger, and the white parts of 4 sliced scallions. Stir-fry for approximately 30 seconds, just until fragrant. Don’t let the garlic burn.
Add the 4 cups cold rice and spread it into an even layer against the hot pan. Let the rice cook undisturbed for 2 minutes so the bottom begins to crisp, then toss and stir-fry for another 2 minutes.
Push the rice to one side of the pan. Pour the 4 beaten eggs into the empty space and scramble for 1 to 2 minutes, until just set. Stir the eggs into the rice.
Add 2 cups roughly chopped chipotle braised pork and 1½ cups thawed frozen peas or corn. Stir-fry for 2 to 3 minutes, until the pork and vegetables are heated through.
Pour 4 tablespoons soy sauce and 1½ tablespoons toasted sesame oil evenly over the rice. Toss everything together for approximately 1 minute, making sure the rice is evenly seasoned.
Remove the pan from the heat. Stir in the green parts of the 4 sliced scallions, then taste and add more soy sauce if needed.
Divide the fried rice among 4 bowls. Finish with sesame seeds and chili oil or sriracha as desired, then serve immediately.
