Step 1: Prepare the Filling : Heat 1 teaspoon of vegetable oil in a skillet over medium heat. Sauté garlic and ginger for about 30 seconds until fragrant. Add cabbage, carrots, bell pepper, bean sprouts, and green onions. Stir-fry for 3–5 minutes until vegetables are slightly softened but still crisp. Add soy sauce, sesame oil, salt, and pepper. Mix well and remove from heat. Let the filling cool slightly.
Step 2: Assemble the Egg Rolls : Place a wrapper on a flat surface with one corner pointing toward you. Spoon 2 tablespoons of filling near the corner closest to you. Fold the corner over the filling, fold in the sides, and roll tightly. Use a little water to seal the edge.
Step 3: Cook the Egg Rolls : Option 1: Baking (Healthier) ,Preheat oven to 400°F (200°C). Place rolls on a parchment-lined baking sheet and brush lightly with vegetable oil. Bake for 15–20 minutes, turning halfway through, until golden and crispy. Option 2: Frying (Traditional) Heat 1–2 inches of vegetable oil in a skillet over medium heat. Fry rolls in batches for 2–3 minutes per side until golden brown. Drain on paper towels.
Step 4: Prepare the Soy Dipping Sauce : Mix soy sauce, rice vinegar, sesame oil, honey, and chili flakes in a small bowl. Garnish with chopped green onion if desired.
