Method

1. Peel the red onion and slice it into thin rings. Sweat it in a frying pan with half the oil over low heat, covered, for 10 minutes, until soft and translucent; add the balsamic vinegar, turn up the heat and cook for 1–2 minutes until glossy and glazed. Set aside.
2. Meanwhile finely chop the rosemary and mix it into the turkey mince with salt and pepper; shape a patty about 1.5 cm thick, with a slight dip in the centre so it doesn't puff up as it cooks.
3. Wash and dry the lettuce; wash the tomato and slice it into rounds.
4. Heat the remaining oil in a frying pan over medium-high heat and cook the burger for 5 minutes per side, until golden outside and no longer pink inside: turkey must be cooked through.
5. Split the burger bun and toast the cut sides in a dry pan for a minute, until crisp.
6. Fill the bun with lettuce, the burger, caramelised onion and tomato.
