Place all ingredients except pork in small saucepan. Bring to low boil until blueberries have collapsed & sauce starts to thicken, about 10 mins. Let cool slightly. Place pork in shallow baking dish just large enough to hold it. Season with salt & pepper and pour blueberry mix over pork. Marinate in fridge up to 30 mins, if time allows. Preheat grill/broiler to high. Remove pork from marinade & return leftover marinade to saucepan. Grill/broil pork for about 4 to 5 mins per side. Lower heat to medium & cook for about 15 mins (internal temperature of 145 degrees). While pork is cooking, bring blueberry marinade to a BOIL & continue to boil for 5 mins, stirring frequently so it does not stick. Serve pork with extra blueberry sauce on side.
