Step 1

Heat 1 tablespoon oil in a frying pan over medium heat. Cook shallot and garlic, stirring, for 2 minutes or until soft. Transfer to a food processor. Add chickpeas, carrot, feta and egg, and process until combined. Transfer to a bowl. Season with salt and pepper. Add the breadcrumbs and mix until combined. Divide mixture into 4 equal portions. Shape each portion into a 6mm-thick, 10cm-diameter patty.

Step 2

Heat the remaining oil in a non-stick frying pan over medium heat. Cook the patties for 4 minutes each side or until browned and cooked through.

Step 3

Meanwhile, preheat grill on high. Cook the bread under grill for 2 minutes each side or until lightly toasted.

Step 4

Divide half the bread, cut-side up, among serving plates. Spread with a little tzatziki. Top with spinach, tomato, chickpea patty, cucumber and mint. Top with a dollop of tzatziki and the remaining bread.
