Heat the olive oil and red pepper flakes in a large skillet
Add the halved artichoke hearts and allow to cook, undisturbed, until they take on some color
Stir in the orange peel, capers and a splash of white balsamic vinegar. Be gentle when stirring so you don't break up the hearts.
Right before serving mix in the parsley.
To serve, arrange the halved artichoke hearts on a small plate with the parsley, capers and orange peel. Drizzle a bit of olive oil around the plate.
