• Preheat oven to 240°C/220°C fan-forced. • Cut potato into bite-sized chunks, then place in a baking dish. • Drizzle with olive oil, season with salt and toss to coat. Roast until almost tender, 20-25 minutes. • When the potato has 10 minutes remaining, thinly slice leek, celery and button mushrooms. Slice lemon into wedges. Little cooks: Help toss the potato chunks.

• Meanwhile, cut chicken breast into 2cm chunks. • Heat a large frying pan over high heat with a drizzle of olive oil. When oil is hot, cook chicken, tossing occasionally, until browned and cooked through, 5-6 minutes. • Reduce heat to medium-high heat. Cook diced bacon, leek, celery and mushrooms, breaking bacon up with a spoon, until golden, 5-6 minutes. • Add garlic & herb seasoning and the plain flour and cook until fragrant, 1 minute. • Add the milk and a squeeze of lemon juice and cook, stirring, until reduced, 2 minutes. Season to taste.

• Pour creamy filling over potato in the baking dish. • In a small heatproof bowl, add the butter, then microwave in 10 second bursts until melted. • Lightly scrunch each sheet of filo pastry and place on top of pie filling to completely cover. Gently brush melted butter over to coat. • Bake pie until golden, 15-20 minutes. Little cooks: Take the lead and help scrunch the filo pastry.

• Divide creamy chicken, bacon and mushroom pie between plates. Enjoy!
