• Cut potato into fries.
• Set air fryer to 200°C. 
• Place fries into the air fryer basket, drizzle with olive oil, season with salt and toss to coat. Cook for 10 minutes.
• Shake the basket, then cook until golden, a further 10-15 minutes. Divide between  serving plates. 

TIP: No air fryer? Preheat oven to 240°C/220°C  fan-forced. Place fries on a lined oven tray. Drizzle with olive oil, season with salt and toss to coat. Bake 
until tender, 20-25 minutes.  

• Meanwhile, thinly slice onion (see ingredients).
• In a large frying pan, heat a drizzle of olive oil over medium-high heat. Cook onion, stirring, until softened, 5-6 minutes.
• Add the balsamic vinegar, brown sugar and a splash of water and mix well. Reduce heat to medium and cook until dark and sticky,  3-5 minutes. Transfer to a bowl. 

• While the onion is cooking, in a large bowl, combine beef & pork mince, fine breadcrumbs (see ingredients) and the egg. Season with pepper and mix well.
• Using damp hands, shape mince mixture into 2cm-thick patties (1 per person). 

TIP: Make a shallow indent in the centre of each patty to help prevent it puffing up as it cooks.

• Wash and dry the frying pan, then return to medium-high heat with a drizzle of olive oil. 
• When oil is hot, cook patties until browned and cooked through, 4-5 minutes each side.
• In the last 1-2 minutes of cook time, sprinkle shredded Cheddar cheese over patties and cover with a lid (or foil) until cheese melts. 

• Meanwhile, halve burger buns and toast or grill to your liking.
• Thinly slice cucumber (see ingredients).
• In a medium bowl, combine mixed salad leaves and a drizzle of white wine vinegar and olive oil. Season to taste with salt and pepper. 

• Spread burger bun bases with some Italian truffle mayonnaise.
• Top with a beef and pork patty, some caramelised onion, cucumber and dressed salad leaves.
• Serve with fries and any remaining truffle mayo. Enjoy!
