Watch Curtis Stone prepare this recipe on Biggest Loser.
Preheat a grill or grill pan on medium high heat.
Place the orange juice into a small saucepan and cook over medium heat until the orange juice has the consistency of a very thin syrup. Add the Dijon, honey, garlic, and ginger and continue cooking over medium heat for 2 to 3 minutes. Remove from heat to allow flavors to meld and reserve.
Evenly divide the cubed chicken among the rosemary sprigs and skewer the chicken onto the exposed part of the rosemary sprigs.
Lightly brush the grill with oil and grill chicken for 1 to 2 minutes on each side or until the internal temperature of the chicken reaches 165 degrees F on an instant read thermometer.
Remove skewers from the grill to a serving plate, drizzle with the orange sauce and serve immediately.
