Add the pork, coleslaw, chopped onions, grated ginger, sesame oil, and soy sauce to a large bowl. Mix until well combined, then place into a skillet and cook over medium heat until pork is no longer pink.

Meanwhile, cook the rice noodles as directed on the package (these cook quickly so drain right away once cooked).

Add noodles to the pork mixture and toss to combine. Serve with pineapple on the side.
