This summery vegetarian side may be quick and easy, but the colorful shingled veggies make for an impressive presentation. Even the most reluctant vegetable-eaters won't be able to resist that cheesy herbed breadcrumb topping.
Step 1
Preheat oven to 400°. Arrange zucchini and tomato slices in overlapping rows in a 9”-x-13” baking dish. Drizzle 2 tablespoons olive oil over vegetables and season with salt and pepper.
Step 2
Combine bread, Parmesan, fresh herbs, garlic, 1/2 teaspoon salt, and red pepper flakes, if using, in the bowl of a food processor or mini chopper and pulse until the mixture has broken down into crumbs. Transfer to a medium bowl, toss with remaining 1 ½ tablespoons olive oil and season with pepper. Scatter breadcrumb mixture over vegetables in an even layer.
Step 3
Bake until zucchini is tender and breadcrumbs are golden, 30 to 35 minutes. Let cool 5 minutes before serving.
