My favs are:

Corn on the cob straight on the bbq.

Chop some veggies (carrots, zucchini, potato, sweet potato, etc) into sticks and spray with oil and sprinkle herbs on then cook on the bbq hotplate.

Get some nice crusty bread cut into thick slices and put garlic butter or herb butter on both sides, brown each side on the bbq.

Coles have really nice honey bbq sausages, I like those and I dont like normal ones.
