04 - Remove roasted peppers from the oven and gently fill each half with the prepared feta mixture.
05 - Return the stuffed peppers to the oven and roast for an additional 10 minutes, until the filling is just golden and the peppers are tender.
06 - Sprinkle with extra fresh parsley prior to serving. Serve warm or at room temperature.
