Roasted Vegetable & Feta Sandwiches
Inspired by that famous New Orleans sandwich, the muffaletta, this jazzy vegetarian version is actually good for you.
Make Ahead Tip: The sandwiches will keep, well wrapped, in the refrigerator or a cooler with a cold pack for up to 8 hours.
To oil a grill rack: Oil a folded paper towel, hold it with tongs and rub it over the rack. (Do not use cooking spray on a hot grill.)
