Preheat BBQ to medium-high. As soon as grill is hot, clean with a grill brush. Place sausages on grill and cook for 8-10 minutes, turning a few times. A few minutes before sausages are done cooking, add buns to the grill and toast lightly.
Remove sausages and buns from grill, and place one sausage in each bun. Top with sun-dried tomato and garlic sauce, shredded lettuce and shredded cucumber.
Serve immediately. 1-2 ciabatta buns per serving. Serve with vegetable chips and a tomato and black olive salad on the side.
