Preheat your oven to 200℃. Chop the potato into wedges about the size of your index finger (no need to peel). Pop them onto a large baking tray in a single layer and drizzle over some oil and a pinch of salt. Give the tray a good shake and then roast on the top shelf of your oven until golden and crispy, about 30 mins. Turn halfway through to make sure they brown evenly. Halve the burger buns.

Halve, peel and thinly slice the onion. Heat a drizzle of oil in a large frying pan on medium-high heat. Once hot, add the onion and stir-fry until soft and golden, 6-8 mins, then remove from the heat. Meanwhile, roughly chop the cranberries and finely grate the cheddar cheese. Quarter the apple, remove the core, chop into small chunks. Put the balsamic vinegar in a medium bowl, add a drizzle of olive oil and a pinch of salt and pepper.

Put the sausage meat in a mixing bowl and add the dried cranberries. Once the onion is cooked, add half to the bowl. Mix with your hands until well combined, then shape into patties (one per person). TIP: To stop the mixture getting too sticky, wet your hands slightly first. Remember to wash your hands after handling raw meat! Put the remaining onion in a bowl and set aside.

Pop your frying pan back on medium high heat with a drizzle of oil. When hot, lay in the burgers. Cook for 11-14 mins. Carefully turn them two or three times to stop them burning (although you do want them nicely browned). Tip: The burgers are cooked when they are no longer pink in the middle. Meanwhile, add the apple to the balsamic dressing and stir to combine.

When the burgers are cooked, remove the pan from the heat. Divide the remaining onion between the tops of the burgers, followed by the grated cheese. Add a splash of water to the pan and place a lid on the pan (or wrap tightly in foil). Lower the heat for the cheese to melt, 3-4 mins. Just before the chips are ready, pop the burger buns on the middle shelf of your oven to warm through, 2 mins.

Spread a little apple chutney on the burger bun base, then place the burgers in the buns. Serve with the chips on the side. Add the rocket to the dressing and apple and toss to combine. Serve the salad alongside the burger. Enjoy!
