• 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, combine beef & pork mince, fine breadcrumbs (see ingredients) and the egg in a large bowl. 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. Little cooks: Join the fun by helping combine the ingredients and shaping the mixture into patties!

• 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. TIP: Cook in batches if your pan is getting crowded.

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

• Spread bases of burger buns with some Italian truffle mayonnaise. • Top with a cheesy beef and pork patty, some caramelised onion, cucumber and dressed salad leaves. • Serve with fries and any remaining truffle mayo. Enjoy! Little cooks: Take the lead and help build the burgers!
