Heat vegetable oil in a large skillet over medium-high heat.
Add the cabbage or coleslaw mix, sausage, garlic, and ginger to the skillet and saute until tender, or cooked through about 3 minutes.
Pour in rice wine vinegar, soy sauce, granulated sugar, salt, sesame oil, and black pepper and toss to combine.
Remove from heat and let cool slightly.
Beat the egg in a small bowl and whisk in 1 tsp. water.
Add oil to a fryer and preheat to 375F.
Place 1 tbsp. of the filling in the center of each egg roll wrapper and roll up tightly.
Brush egg on the top edge to seal the egg roll.
Fry egg rolls in small batches until golden brown, about 3 minutes.
ENJOY!!
