Heat a large skillet or wok over medium-high heat. Add the bite sized pieces of pork belly and cook until it's browned and crispy, about 5-7 minutes.
Remove the pork belly from the skillet and set it aside. Remove excess fat with a paper towel.
In the same skillet or wok, add the olive oil and heat it over medium heat.
Add the broccoli, diced carrots, peas, ground ginger, garlic powder, and black pepper and cook for another 2-3 minutes, or until they start to soften.
Add the leftover cold rice to the skillet. Break up any clumps and stir-fry the rice with the vegetables for a few minutes.
Return the cooked pork belly to the skillet. Stir everything together.
Add the coconut aminos and sesame oil. Continue to stir-fry for a few more minutes, making sure the sauce is evenly distributed.
Taste the fried rice and adjust the seasonings, if needed.
Garnish with chopped green onions.
