Step 1
To make the mint-feta pesto, in a blender or food processor, combine the mint, pine nuts, and red pepper flakes and pulse until the mint is chopped. With the machine running, slowly add the 1/2 cup olive oil in a thin, steady stream, processing until thin paste forms. If the paste is too thick, add a little more olive oil. Add the cheese and pulse 3 or 4 times to mix. Alternatively, for a more rustic sauce, transfer the mint mixture to a bowl and stir in the feta just until combined. Season with salt and black pepper. Use immediately, or cover and refrigerate for up to 3 days. Bring to room temperature and stir just before serving.
