Clean the pork by trimming it of any excess fat and silver skin. Cut into 1/2 inch medallions on the diagonal.
In a small bowl, whisk together the soy sauce, 2 Tbsp. rice vinegar, 2 Tbsp. brown sugar, garlic, ginger, 1/2 Tbsp. sesame oil, 2 tsp. Sriracha. Add 1/2 cup of the sauce to the pork medallions in a large bowl.
Massage into the meat. Reserve the other half for a sauce. Let the pork stand for 25 min. or in the refrigerator for up to 2 hours.
While the pork is marinating, toss the cabbage with the carrot and half the green onions.
In a small bowl whisk together 1 Tbsp. canola oil, 1 tsp. salt and 2 Tbsp. rice vinegar, 1 Tbsp. brown sugar, 1/2 Tbsp. sesame oil and 1 tsp. Sriracha.
Toss the slaw with the dressing and serve on a large platter or keep in the bowl to serve on individual plates.
Heat 2 Tbsp. canola oil in a large nonstick frypan over medium-high heat. When the pan is very hot add the pork after taking it out of the marinade and shaking off excess.
Cook the pork in 2 or 3 batches so as not to crowd the frying pan adding more oil as needed. Let the pork cook without moving until very brown about 2-3 min., flip the pork and cook for another 2-3 min. until the pork is cooked through. Check by slicing into a piece.
Serve the pork on top of the slaw on a serving platter or individual plates drizzled with the reserved sauce and sprinkled with the reserved green onions.
