• Wash and dry produce. Halve baguettes lengthwise; top cut sides of each baguette with a drizzle of olive oil, salt, and pepper. Toast until golden. TIP: Gently scoop out some bread from cut sides to make room for all the creamy burrata.

• Trim and slice zucchini crosswise into 1⁄4-inch-thick rounds. Slice tomato into 1⁄4-inch-thick rounds; lightly season with salt and pepper.

• Lightly drizzle zucchini with olive oil; season with salt and pepper. Place on a microwave-safe plate; microwave until steamed, 3 minutes.

• While zucchini steams, spread pesto onto cut sides of baguettes.

• Top bottom halves of baguettes with burrata; slice into burrata to spread. Top with as much zucchini as you like. (Save any remaining zucchini for another use.) Fan tomato over top and drizzle with balsamic glaze. Close sandwiches and serve.
