In a small bowl, combine the cornstarch, water, soy sauce and ginger until blended; set aside. In a large skillet, saute pork and garlic in oil for 3-5 minutes or until meat is no longer pink.
Stir cornstarch mixture and add to the skillet. Bring to a boil; cook and stir for 1-2 minutes or until thickened. Stir in hoisin sauce. Add coleslaw mix; stir to coat. Spoon about 1/2 cup pork mixture into the center of each tortilla; roll up tightly.
