Lamb, spinach & ricotta burgers

Heat 2 Tbsp oil in a large non-stick frying pan over medium heat. Add sliced onions and cumin seeds. Stir well. Reduce heat to medium-low and cook, stirring occasionally, for 20 minutes or until onions soften and start to caramelise.

Meanwhile, put spinach in a colander and pour over a kettle of boiling water to wilt. Squeeze spinach to remove as much liquid as possible. Roughly chop and put in a large bowl.

Add mince, grated onion, ricotta and pepper to spinach. Mix until well combined. Shape into 4 patties. Heat remaining oil in a large non-stick frying pan over medium heat. Add patties and cook for 4-5 minutes each side, or until cooked through.

Combine yoghurt, mint and pepper in a bowl. Spread a little on roll bases. Add tomato and patties. Top with onions and roll tops. Serve yoghurt mix on side.
