For the burgers, place all of the burger ingredients, except the flour and oil, in a food processor and pulse until well combined. Using damp hands, shape the mixture into two patties, then dust with the flour.
Heat the olive oil in a frying pan and fry the patties for 3-4 minutes on both sides, or until golden-brown and cooked through.
For the salad, combine all of the salad ingredients in a bowl and mix well.
To serve, place one patty on each slice of bread and arrange the salad on top.
