COOK IT.
Prepare the vegetables for the caponata on the Keg or your Broil King Pellet grill as outlined in our vegetable cooking chart. Let cool completely. Dice all the vegetables and place them in a medium bowl with the herbs and spices and feta cheese. Toss gently to combine.
Cut the peppers in half lengthwise and remove the seeds and ribs. Spoon in the smoked vegetable mixture. In a small bowl, toss the breadcrumbs with butter, and sprinkle this on top of the stuffed peppers. Sprinkle some parmesan cheese on top.
To help keep the peppers steady and level, and to preserve their shape, you may want to place each one into an empty small flan ring. Roast them on the top rack or warming rack of the Keg or pellet grill for 20-30 minutes or until tender at MEDIUM heat, approximately 375F (190C).
