Preheat the barbecue, oiled ridged grill pan or heavy nonstick skillet. Trim eggplant; cut crosswise into 1/2-inch (1-cm) slices. Spray slices on both sides with baking spray; sprinkle lightly with salt and pepper. Cook over medium heat (with barbecue lid down) for 8 to10 minutes, turning once, until tender and marked with grill marks (you may have to cook slices in batches if using a grill pan or skillet).
Meanwhile, split buns; toast cut sides down on barbecue or put cut sides up under a hot broiler for about 1 minute, until lightly toasted. Spread bottom halves of each bun with pesto; top each with watercress, then with 2 or 3 slices of eggplant. Divide cheese evenly among buns.
Replace tops of buns; serve at once.
