In a large nonstick skillet, heat the oil over medium-high heat. Add the light scallions and ginger and cook, stirring constantly, for 2 minutes. Add the garlic and cook 20 seconds more; do not brown. Add the pork and continue cooking, breaking the meat apart with a wooden spoon, until browned, 3 to 5 minutes.
Add the coleslaw and soy sauce to the skillet and cook, stirring occasionally, until wilted and cooked through, 5 to 7 minutes.
Stir in the sweet and sour sauce, sesame oil, cashews, and dark green scallions. Taste and adjust seasoning, if desired. Serve with sweet and sour sauce on the side.
