- 4 large plum tomatoes, quartered
- 1 large onion, cut into 1/2-inch-wide wedges
- 2 red or green bell peppers, sliced
- 1 8-ounce zucchini, trimmed, halved lengthwise, sliced crosswise
- 1 tablespoon olive oil
- Nonstick vegetable oil spray
- 1 cup dry breadcrumbs

- 4 skinless boneless chicken breast halves
- 1/4 cup freshly grated Parmesan cheese
- 2 tablespoons chopped fresh Italian parsley

- Preheat oven to 400°F. Place vegetables on large rimmed baking sheet. Sprinkle with salt and pepper. Drizzle oil over; toss to coat. Roast vegetables until tender and brown around edges, turning occasionally, about 45 minutes. Remove from oven. Increase oven temperature to 500°F.
- Meanwhile, spray large nonstick baking sheet with oil spray. Place breadcrumbs on sheet of waxed paper. Whisk egg whites in shallow bowl until foamy. Using mallet, pound chicken breasts to 1/3-inch thickness. Sprinkle chicken with salt and pepper. Turn chicken in breadcrumbs; place on platter. Stir Parmesan into remaining breadcrumbs on waxed paper. Dip chicken into egg whites to coat. Then dip chicken into Parmesan breadcrumbs to coat; shake off excess.
- Transfer vegetables to bowl; mix in parsley and thyme. Add broth to baking sheet; scrape up any browned bits. Pour over vegetables. Keep warm.
- Bake chicken on prepared sheet 5 minutes. Turn chicken over; bake just until cooked through, about 5 minutes longer. Transfer chicken to plates. Spoon vegetable sauce alongside.
