• Set air fryer to 200°C. • Cut potato into fries. • In a medium bowl, combine fries, a drizzle of olive oil and a pinch of salt and pepper. • Place fries into the air fryer basket and cook for 15 minutes. Shake the basket, then cook until golden, a further 10-15 minutes. • Divide fries 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 brown onion. • Thinly slice tomato. Little cooks: Don your goggles and have a go at peeling off the onion's outer layer!

• In a large frying pan, heat a drizzle of olive oil over medium-high heat. Cook onion, stirring regularly, until softened, 5-6 minutes. • Reduce heat to medium. Add the balsamic vinegar, brown sugar and water, then mix well. Cook until dark and sticky, 3-5 minutes. • Transfer to a small bowl.

• When fries are done, place bake-at-home ciabatta in the air fryer basket and cook until heated through, 2-3 minutes. TIP: No air fryer? Place ciabatta directly on a wire rack in the oven. Bake until heated through, 5 minutes.

• When the potato fries have 5 minutes remaining, place beef rump between two sheets of baking paper. Pound beef with a meat mallet or rolling pin until slightly flattened. • In a medium bowl, combine Italian herbs, a good pinch of salt and pepper and a drizzle of olive oil. Add beef, tossing to coat. • Wipe out frying pan, then return to high heat with a drizzle of olive oil. When oil is hot, cook the beef, turning, for 3-6 minutes (depending on thickness), or until cooked to your liking. Transfer to a plate to rest. Little cooks: Help toss the beef in the seasoning. Make sure to wash your hands well afterwards! TIP: If your beef rump is more than 3cm thick, cut in half horizontally before pounding for a shorter cook time.

• Slice each ciabatta in half, then spread with creamy pesto dressing. • Top with beef, caramelised onion, tomato slices and baby spinach leaves. Top with other ciabatta half. • Serve with potato fries. Enjoy! Little cooks: Take the lead and help build the subs!
