Instructions

  1. 1

    Preheat oven to 400F

  3. 3

    Toss toasted bread, 2 tablespoons of olive oil, thyme, oregano, salt, black pepper, red pepper flakes, and parmesan together in a bowl. Set aside.

  4. 4

    Alternate tomato and zucchini slices in a shallow baking pan.

  5. 5

    Season with salt and pepper.

  6. 6

    Whisk together remaining olive oil, red wine vinegar, minced garlic and shallot. Pour over tomatoes and squash.

  7. 7

    Top evenly with bread crumb mixture.

  8. 8

    Bake on the middle rack at 400°F for 20 minutes, or until the zucchini is fork-tender and the breadcrumbs are toasty. If it is getting too dark, tent with foil.

  9. 9

    Tear basil leaves on top and serve warm or at room temperature.
