If using wooden skewers, pre-soak 40 of them in cold water for at least an hour.

Thread one slice of zucchini, one slice of sausage, and one shrimp onto each skewer. Any order will do but it makes for a nice presentation if you keep them all the same and curl the shrimp around the curve of either the zucchini or sausage.

Season the skewers with salt and pepper then cook them on a hot grill (or if cooking inside you could use a grill pan) for 3-4 minutes on each side.

Once the skewers are cooked, lay them out on a platter and serve with the barbecue sauce.
