• 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. Pick thyme leaves (see ingredients). Little cooks: Help toss the potato chunks.

• Heat a large frying pan over medium-high heat with a drizzle of olive oil. 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 cook, stirring, until reduced, 2 minutes. Season to taste. TIP: Cook in batches if your pan is getting crowded.

• Pour creamy filling over potato in the baking dish. • In a small microwave-safe 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 bacon and mushroom filo pie between plates. Enjoy!
