Avocado and feta cheeseburger

Method

1. Heat a ridged griddle pan or prepare a barbecue for high direct heat. Brush the burgers with oil and cook for 6-8 minutes until cooked through and well browned.

2. While the burgers are cooking, put the avocado in a small bowl and roughly mash with the lime juice, coriander, chilli flakes (if using) and a good pinch of salt.

3. Spread each burger bun base with a dollop of mayonnaise and a good helping of the avocado mixture. Divide the lettuce and tomato and burger patties between the buns, then top with the rest of the avocado, a few pickled red onions and some crumbled feta. Pop the burger tops on and serve.
