In a large mixing bowl, combine the ground chicken, minced garlic, shredded cabbage, shredded carrots, finely chopped green onions, soy sauce, sesame oil, ground ginger, salt, and pepper. Mix well until all ingredients are evenly incorporated.
Preheat your oven to 400°F (200°C). This ensures that your Baked Egg Rolls will cook evenly and become crispy.
Lay an egg roll wrapper on a clean surface, with one corner pointing towards you. Place about 2 tablespoons of the filling on the lower third of the wrapper. Fold the bottom corner over the filling, then fold in the sides and roll up tightly. Seal the top corner with a little water. Repeat with the remaining wrappers and filling.
Lightly spray a baking sheet with cooking spray. Place the assembled egg rolls seam-side down on the baking sheet. Make sure to leave space between each egg roll.
Spray the tops of the egg rolls lightly with cooking spray. Bake in the preheated oven for 20-25 minutes, or until golden brown and crispy, flipping halfway through.
