Having a BBQ soon? Why not try our tasty beef burgers

Beef burger with sweet potato chilli chips


4 large, roundish sweet potatoes cut into chunky chips
1 tsp olive oil
1 tsp chilli flakes, plus a pinch
400g pack extra-lean beef mince
1 onion, grated
1 tbsp grated parmesan
1 tbsp tomato ketchup
4 small wholemeal buns, halved
1 Little Gem lettuce, leaved separated
1 beef tomato, sliced
1 red onion, sliced (optional)
4 pickles or gherkins, halved 

Heat oven to 220C/200C fan/gas 7. Toss the chips with the oil, 1 tsp chilli flakes and some seasoning. Arrange in a single layer on a large baking tray and cook for about 30 minutes, turning halfway through.

Put the mince, remaining chilli flakes, onion, Parmesan, tomato ketchup and lots of black pepper in a large bowl and mix to combine. Shape into 4 burgers. Ten minutes before the chips are ready, put the burgers on a baking tray and bake for 10 minutes or place on the BBQ until cooked through.

Top one half of the buns with the lettuce, tomato and onion. Add the burgers, and then top with the roll tops. Serve with chips and pickles on the side.
