Greek lamb and haloumi burgers

1.Heat barbecue or char-grill pan over high heat. Using your hands, combine mince, egg, oregano, cumin, most of the garlic, sea salt and pepper in large mixing bowl. Quarter mixture and roll into 4 even patties. Flatten and place on tray.

2.To make tzatziki: grate cucumber onto tea towel. Pull corners of towel together and wring out cucumber over sink to remove excess water. Place in small mixing bowl with yoghurt, mint and remaining garlic. Stir to combine. Season with salt and pepper to taste.

4.Place bread on grill plate 30-60 seconds each side to lightly toast.

5.Place base of toasted bread on each plate and spoon over some of the tzatziki. Add spinach leaves, burger and haloumi. Top with onion and remaining slice of toasted bread (or leave bread off for an open burger).
