In a pan over medium heat, cook ground pork until browned. Add cabbage, carrots, green onions, ginger, soy sauce, and sesame oil. Stir-fry for 3–4 minutes until vegetables are tender. Let the mixture cool.
Place an egg roll wrapper on a clean surface. Spoon 2 tablespoons of filling onto the center. Fold the bottom corner over the filling, fold in the sides, and roll tightly. Seal the edges with cornstarch slurry.
Heat 2 inches of vegetable oil in a deep pan to 350°F (175°C). Test by dipping a small piece of wrapper—if it sizzles, the oil is ready.
Carefully place egg rolls in the hot oil and fry for 3–4 minutes per side until golden brown. Drain on a paper towel-lined plate.
Let the egg rolls cool for a few minutes, then serve with your favorite dipping sauce, like sweet and sour sauce or soy sauce.
