2 leeks, trimmed and halved lengthways, then again widthways
4 heads of chicory, halved lengthways
3 tbsp olive oil
1 tbsp red wine vinegar
Salt and freshly ground black pepper
Method
Preheat the barbecue to a medium/high heat.
Place the leeks and chicory onto a sheet of foil and fold up the edges to make an open-topped packet. Pour over the dressing; make sure the vegetables are evenly covered.
Grill until the chicory is slightly golden and the leeks are tender, 10 to 12 minutes.
