Spoon 1/4 cup beef, 2 tablespoons carrots and 2 tablespoons cilantro evenly in a row across center of wrapper, leaving 1-inch border on right and left sides; drizzle with about 1 teaspoon reserved stir-fry sauce. Fold right and left sides of wrapper over filling. Fold bottom edge up over filling and roll up tightly. Repeat with remaining wrappers and filling ingredients. Cut each spring roll diagonally in half. Serve with additional stir-fry sauce, if desired.
