Preparation / Directions:
In small saucepan, combine orange juice, vinegar, kosher salt and pepper and bring to boil over high heat. Reduce heat to medium-low and simmer vigorously until liquid is reduced by half; about 20 minutes. Remove from heat and set aside.
In medium bowl, combine pork cubes, apples, olive oil, and salt and pepper to taste, and toss well.
Thread pork and apples alternately onto skewers and grill over medium-hot fir for 5-7 minutes, turning several times.
To check for doneness, cut into one of the pieces of pork; it should be just pink in center. During last 30 seconds of cooking brush skewers with some of the glaze.
Remove skewers from fire, drizzle with remaining glaze, and serve.
