I do my lamb roasts on the bbq (my bbq has a rotisserie which is brilliant) - I poke some holes in the leg of lamb with a knife and then squish in some chopped garlic and rosemary leaves - yummo and I put some water and more garlic and rosemary in the drip tray at the bottom and catch the juices from the meat to make the gravy.

My other fave bbq is corn on the cob like Ali...I brush sweet chilli or normal chilli sauce over the corn and bbq it - yum!
