From the Test Kitchen

Tonight’s hearty vegetarian sandwiches take their irresistible flavors from a Vietnamese favorite: bánh mì. Between slices of the traditional crunchy baguette, a tender layer of ginger-sautéed mushrooms finds refreshing contrast in tangy-sweet marinated carrots and cucumber—all brought together with spicy sriracha mayonnaise. For our side, we’re roasting gai lan until the leaves turn slightly crispy, then dressing it with the flavorful marinade from our vegetables.

Peel and roughly chop the ginger. Halve the baguettes.Thinly slice the cucumber into rounds. Peel the carrots and grate on the large side of a box grater. In a medium bowl, combine the cucumber, carrots, sugar, and vinegar. Season with salt and pepper. Set aside to marinate, stirring occasionally, for at least 10 minutes. Season with salt and pepper to taste.

Arrange in an even layer. Roast, stirring halfway through, 12 to 14 minutes, or until lightly browned and tender when pierced with a fork. Remove from the oven. Reserving the marinating liquid, drain the marinated vegetables. Top the roasted gai lan with the reserved marinating liquid. Carefully stir to coat. Season with salt and pepper to taste.

Add the ginger; season with salt and pepper. Cook, stirring constantly, 30 seconds to 1 minute, or until fragrant. Turn off the heat; season with salt and pepper to taste.

5 Toast the baguettes:

Place the baguettes on the same sheet pan, cut side up. Drizzle with olive oil and season with salt and pepper. Toast in the oven 4 to 6 minutes, or until the edges are lightly browned. Remove from the oven and carefully transfer to a cutting board.
