Start by softening your cream cheese at room temperature so it’s smooth and easy to mix. In a bowl, combine the cream cheese, garlic salt, and chopped green onions. Stir until everything is evenly mixed and creamy. This will be your flavorful filling.
Lay one egg roll wrapper flat on a clean surface. Place about 2 tablespoons of the cream cheese mixture on the lower third of the wrapper. Dip your finger in a little water and moisten the top edge of the wrapper. Roll the wrapper tightly around the filling, folding the sides in as you go, and press the edge to seal. Repeat until all the filling is used.
Lightly brush or roll each filled wrap with vegetable oil to help them brown evenly. Arrange the rolls on a lined baking sheet, spacing them out so they don’t touch. Bake in a preheated oven at 375°F (190°C) for 12–15 minutes, turning once halfway through, until golden brown and crispy. Let them cool slightly before serving.
