Melt the butter in a pan. Add the artichokes and thyme leaves and sauté for 5-6 minutes, to soften.
Add the cavello nero and cook to soften for 4-5 minutes, stirring occasionally.
In a separate frying pan, heat a tablespoon of olive oil. Season the pheasant thighs with salt and freshly ground black pepper, place in the pan and cook for 5-6 minutes on each side, until golden and thoroughly cooked.
To serve, transfer the artichoke mixture to a serving dish. Top with the pheasant thighs and sprinkle with parsley.
