Preparation
Heat oven to 450°F. Toss eggplant, zucchini, bell pepper
and onion with 2 teaspoon oil in a bowl. Add thyme; season with salt
and pepper and toss again. Coat a shallow baking pan with cooking spray.
Arrange vegetables on pan and roast until tender, about 20 minutes.
Stir in garlic and marinara. Cover loosely with foil and roast 10
minutes more. Remove pan from oven. Stir in chopped basil. Rub fillets
with remaining 2 teaspoon oil; season with salt and pepper. Nestle fish
in vegetables; cover loosely with foil. Bake until fish is just cooked
through, about 10 minutes. Top with basil leaves and capers.
