Dice the pork belly and chicken breast into small, uniform half-inch cubes to ensure even cooking and maximum crispiness.
Place the pork belly in a cold wok or large non-stick skillet over medium-high heat, allowing the fat to render until the pieces are golden and crispy.
Add the cubed chicken breast to the wok with the pork, seasoning both with sea salt and black pepper, and sauté until the chicken is fully cooked through.
Remove the meat from the pan and set aside, leaving about a teaspoon of the rendered fat in the wok for flavor.
Pour the whisked large egg and egg whites into the wok, scrambling them quickly until just set, then remove and set aside with the meat.
Add the sesame oil to the wok followed by the cauliflower rice, green peas, garlic powder, and ginger powder, sautéing for 3-4 minutes until the cauliflower is tender-crisp.
Return the cooked meat and eggs to the wok, drizzling the tamari over the mixture and tossing everything together for 1 minute to incorporate the flavors.
Garnish with thinly sliced green onions and serve immediately while the pork is still perfectly crunchy.
