Step 1

Tip all the beans into a colander and rinse under cold running water. Drain well and pat dry with kitchen paper. Transfer to a large mixing bowl and mash until roughly crushed with a potato masher.

Step 2

Add the breadcrumbs, spring onions, coriander and egg and season with salt and freshly ground black pepper. Mix thoroughly with clean hands then divide shape and divide into four chunky burgers.

Step 3

Place the burgers on a foil-lined grill pan and brush with olive oil. Cook under a medium-hot grill for 5-6 mins on each side until light golden and piping hot.

Step 4

Serve the hot burgers in split burger buns with salad and sliced vegetables.
