Place all ingredients in a 1-gallon self-sealing plastic bag, mix well. Seal bag and marinate in the refrigerator 8-12 hours or overnight. Heat oven to 350 degrees F. Remove pork cubes from marinade, discarding marinade.
Pat pork dry with paper toweling; place cubes in a single layer, not touching, in a shallow baking pan and bake at 350 degrees F. for 25-30 minutes, until pork is just tender and lightly browned. Remove to serving platter or chafing dish and serve hot.
