Heat grill to medium high heat. Rub pork with olive oil, cumin, salt and pepper. Place pork on grill coated with cooking spray. Cover and grill 20 minutes, turning occasionally. Grill until thermometer registers 155º (slightly pink). Let stand for 10 minutes before slicing.
Spread 1 tbsp Marie’s Coleslaw Dressing on both sides of cut deli buns. Add sliced pork to dressed bun and serve. Simple and delicious!
