Preheat that oven to 220C! 🔥

In an oven-safe frying pan, drizzle some olive oil and toss in the bacon, leeks, a pinch of salt and pepper, and chicken. Sizzle till the leeks get all cuddly and soft and your chicken is cooked to perfection. 😋

Time to jazz things up! Stir in the Dijon, stock powder, dill and flour. Once mixed, pour in the cream and watch magic happen as it transforms into a luscious sauce. 🌟

Hit stop on the heat! Layer those fresh spinach leaves right on top – but resist the urge to mix them in. 🚫🥄

Drape the puff pastry sheets over your creamy mixture, giving those corners a little tuck. Before it heads to the oven, give the pastry a little spritz of olive oil. 🌬✨

Into the oven it goes! Bake till it's got that irresistible golden glow – around 20 minutes. 🥧

Slice, serve, and let your taste buds dance! 🍽✨
