Heat your wok or skillet over medium-high heat and add a splash of oil to coat the bottom. Once shimmering, add the ground pork, breaking it apart with a spatula. Cook until it turns golden brown and starts to crisp at the edges, about 5-7 minutes, releasing a savory aroma.
Add the minced garlic and grated ginger to the pork in the pan. Stir constantly for about 30 seconds until fragrant, with a fragrant aroma filling the air and the mixture bubbling lightly.
Stir in the chopped vegetables and cook for another 2-3 minutes until they start to soften and turn vibrant in color, while maintaining some crunch.
Pour in the soy sauce and drizzle with sesame oil if using. Mix everything thoroughly so the sauce coats the pork and vegetables evenly, allowing the flavors to meld together.
Continue to cook for another 1-2 minutes until the mixture is glossy and heated through. The sauce should be slightly sticky, clinging to the meat and vegetables.
Remove from heat and transfer to a serving bowl or plate. Garnish with sliced spring onions for a fresh, crunchy finish.
