1 tablespoon extra-virgin olive oil
1 clove garlic, minced
1 tablespoon Dijon mustard
1 pound pork loin, cut into 1-inch cubes
2 tablespoons pure maple syrup
Kosher salt and freshly ground pepper to taste
1 teaspoon finely chopped fresh rosemary
In a large bowl or plastic container, mix together the olive oil, mustard, maple syrup, rosemary, garlic, salt and pepper until well blended. Add the pork cubes and turn in the mixture to coat; refrigerate for at least 2 hours, or preferably overnight.
Soak 8, 8 to 12-inch wooden skewers in water to cover for at least 30 minutes.
Preheat the broiler or grill. Skewer the pork cubes, dividing them evenly between the skewers. Discard the remaining marinade.
Broil or grill for 6 to 8 minutes total, turning as they brown, until they are just cooked throughout.
