1. Preheat grill to medium-high heat (350° to 400°) or grill pan over medium-high heat. Sprinkle pork evenly with rosemary, salt, and pepper. Grill pork, covered, turning once, 15 minutes or until a thermometer inserted in the thickest part of the meat registers 145°. Cover pork loosely with aluminum foil; let stand 10 minutes before slicing.
2. Melt butter in a large skillet over medium-high heat. Add shallot; cook 1 to 2 minutes or until tender. Stir in chicken stock and next 3 ingredients. Bring mixture to a boil, and cook 1 to 2 minutes, stirring until sugar dissolves. Stir in strawberries, and cook, stirring occasionally, 3 to 5 minutes or until berries soften and mixture thickens slightly. Spoon sauce over sliced pork and rice, if desired. Sprinkle with green onions.
