Method

1. Preheat the oven to 160°C, gas mark 3 and light the barbecue. Crack the egg into a small bowl, add 1 tbsp water and whisk to make an egg wash.

2. Brush the egg wash on top of the brioche buns and sprinkle with the sesame seeds. Place onto a baking tray and cook for 5 minutes, until the seeds are set onto the buns then halve.

3. Cook the burger patties on a hot barbecue for 12-14 minutes, until thoroughly cooked. Place a slice of cheese on top and allow to melt for 1 minute. Toast the sliced buns on the barbecue, cut side down, for 1 minute, until golden.

4. Spread the mayonnaise on the bottom half of each bun. Top with shredded lettuce, then the burger. Add a slice of tomato followed by the gherkins and pastrami slices. Drizzle with mustard and top with the bun.
