This cold salad is full of flavor and goes well with grilled food. Whether you roast the peppers on the grill or in your broiler, the lovely, smoky, roasted flavor really comes through. Roasting peppers is fun, too. They caramelize, turn soft, and are yummy. It takes about 15 minutes to roast peppers on all sides depending on your broiler and size of the peppers. Use a decent feta cheese and fresh herbs for this one.
