Shred or finely chop the meat, dice the squash, finely chop the leeks, mash the potato if not already, peel and crush the garlic and chop the fresh coriander. Add all ingredients except the oil to a large bowl. Mash everything together with a potato masher or a fork until evenly mixed, but still with some texture.

Form the mixture into patties/burgers, approx. 6cm x 1cm deep.

To cook you can either pan fry in a little vegetable oil over a medium heat for approx. 5 minutes on each side, or you can bake in the oven at 200°C / 180°C fan / gas mark 6 for approx. 20 minutes, turning over halfway through. Whichever method you use, ensure the patty is piping hot all the way through, then allow to cool before serving.

For a light bite serve with a mint yogurt dip or as a main meal with salad or green vegetables. You can use different leftover veggies if you like, depending on what you have. Carrots work well instead of the squash and some broccoli or sprouts could replace the leeks. You can also cook up some vegetables or meat specifically for this recipe if you don't have enough leftovers.
