Preheat the oven to 180°C.
Season the chicken breasts with black pepper.
In a pan, heat the olive oil and butter. Dredge the chicken breasts in the flour and fry until golden brown on both sides.
Add the garlic purée and stir to combine.
Pour in the chicken stock and bring to a simmer. Add the double cream, parmesan, chilli flakes, oregano, and Mediterranean seasoning. Stir to combine.
Add the sun-dried tomatoes and the watercress or spinach. Taste and adjust seasoning as needed.
Lay the filo sheets out and brush with the melted butter. Place the chicken breasts on the filo and wrap the filo around the chicken to enclose it.
Place the wrapped chicken on a baking tray and bake in the preheated oven until the filo is golden brown, about 20-25 minutes.
