In a small bowl combine the rice, vinegar, mint, shallots, feta, olive oil and salt and pepper. Lay out the four grape leaves and divide the filling among the leaves, making a small pile in the center of the leaves. Fold the end of the leaf over the filling, fold over the sides, and roll the leaves up. Place on a small plate and drizzle with the vinaigrette.
