When I grew up I remember that at BBQs we normally had a choice between Cucumber salad, a Greek salad, if we were lucky and definitely a Potato salad. Normally with lots of mayonnaise. Later on a platter of Tomato and Mozzarella was refinement par excellence.
For me, the combined smell of burned sausages, freshly cut grass and salad of sorts is the smell of sommer.
Well, this is all in the past and these days a BBQ can easily represent a gourmet walk around the world -lovely!
