Grilled Summer Vegetable Panzanella

Preheat grill to medium.

Brush both sides of zucchini, eggplant, onion and bread with 3 tablespoons oil. Sprinkle the vegetables with 1/4 teaspoon each salt and pepper. Grill the vegetables, turning once, until tender, 4 to 5 minutes per side. Grill the bread until lightly charred in spots, about 3 minutes per side.

Meanwhile, whisk vinegar, garlic and the remaining 4 tablespoons oil and 1/4 teaspoon each salt and pepper in a large bowl. When the vegetables and bread are cool enough to handle, cut them into bite-size pieces and add to the bowl along with the herbs. Toss to coat well. Let stand for 10 minutes before serving. Top with crumbled feta, if using, and more chopped herbs, if desired.
