Slice the pork loin and pork belly into very thin, bite-sized strips.
In a small bowl, whisk together the gochujang, tamari, honey, and toasted sesame oil to create the glaze.
Heat a large wok or cast-iron skillet over medium-high heat.
Add the pork belly strips first, cooking for 2-3 minutes until the fat renders and the edges become crispy.
Add the pork loin strips to the pan and sear for another 3-4 minutes until browned and cooked through.
Stir in the minced ginger and garlic, sautéing for 30 seconds until the aroma is released.
Toss in the chopped bok choy, sliced bell peppers, and snap peas, stir-frying for 3 minutes until the vegetables are tender-crisp.
Pour the gochujang glaze over the pork and vegetables, tossing constantly for 1 minute to ensure everything is thickly coated.
Remove from heat and garnish with sliced green onions and sesame seeds before serving.
