Take the guinea hen breast, slice to create a pocket in the middle and marinade with salt, pepper and thyme.
Place the breast skin side up on a slice of baking paper, roll and pucker either end, like a boiled sweet.
Roll up the meat cut in the baking paper into a sausage shape.
Bake for 12 minutes at 180°.
In the meantime, finely slice the leeks and braise them with the Organic Strained Tomatoes.
Slice the king oyster mushrooms and pan-fry them with some oil, salt, garlic and parsley.
To finish off the recipe, open up the baking paper and sauté the guinea hen on a high flame. Place the meat on a dish with the braised leeks and mushrooms sautéed in olive oil, garlic and parsley.
