1. Take out Wagyu burger from package and rest it to room temp.
2. When you're ready to cook the burgers, get a frying or griddle pan nice and hot. Brush the pan with a little oil, season the burgers generously with salt and pepper, and cook them for 10 minutes, turning them carefully every minute or so, until they're nice and pink and juicy, or longer if you like them well done.
3. Meanwhile, roughly chop the lettuce, tomato and cucumber, mix together and set aside. Once the burgers are cooked, split the rolls into two and toast them quickly on the griddle or in a toaster. Sandwich the cooked 'Elvis' burger between the toasted rolls
4. Serve them on individual plates with the gherkins and some of the chopped salad (add a little extra virgin olive oil or dressing if you like) on the side.
