Ingredients
Instructions
- Adjust rack to top position and preheat oven to 425°F. Wash and dry produce. Slice potatoes into ½-inch wedges. Trim, peel and grate carrot on the largest holes of a box grater; place in a medium microwave-safe bowl. Trim and halve cucumber lengthwise; slice crosswise into ¼-inch-thick half-moons. Roughly chop cilantro, including tender stems. Trim and slice mushrooms into ½-inch-thick pieces.
- Toss potatoes on a baking sheet with a large drizzle of oil, salt and pepper. Roast on top rack until golden brown and tender, 20-25 minutes.
- While potatoes roast, to bowl with carrot, add cucumber, vinegar, ½ tsp sugar and a pinch of salt (1 tsp sugar and a big pinch of salt for 4 servings). Microwave until sugar has dissolved, 30 seconds. Stir in cilantro. Set aside to pickle, stirring occasionally, until ready to use.
- Heat a drizzle of oil in a large pan over medium-high heat. Add mushrooms; cook, stirring occasionally, until browned and slightly crispy, 5-7 minutes. Turn off heat; stir in sweet soy glaze until mushrooms are coated. Transfer to a medium bowl. Meanwhile, halve and toast baguettes.
- Drain veggie pickling liquid into a small bowl. Add mustard and a drizzle of oil; whisk to combine. Season with salt and pepper. Spread cut sides of baguettes with as much spicy mayo as you like. Fill with mushrooms and about half the pickled veggies.
- In a medium bowl, combine mixed greens, remaining pickled veggies and as much dressing as you like; toss to combine. Divide banh mi, potatoes and salad between plates. Serve with any remaining spicy mayo on the side for dipping.
Recipe Tips
For extra crispy mushrooms, avoid overcrowding the pan and cook in batches if needed.

Adjust the amount of spicy mayo to your heat preference.
