Preheat grill to medium-high. Thread tomatoes onto skewers. Brush with vinaigrette and place on grill. Cook 5 to 7 minutes or until some begin to burst and get charred. In a medium bowl, combine tomatoes, feta cheese, green onions and remaining dressing.

Arrange endive leaves around serving platter in a flower petal pattern, with one end of each leaf touching in the center. Mound the tomato mixture in the center of the plate.
