Method
Add all the dry and wet ingredients. The ones I listed are just a (tried&tested) guide: be creative!
Either cover all the slices in oil (marinade) or stir your marinade more often. Be gentle with the courgette. If you don't want to "waste" this much olive oil you can use a mixture of olive and generic vegetable oil.
Give your courgette time to marinate. One hour will be enough, more than four hours will be amazing
Cook for a minute or two each side on a BBQ or frying pan
