Wash and dry all produce. Adjust rack to middle position and preheat oven to 400 degrees. Halve, peel, and finely chop shallot. Zest lime until you have 1 tsp zest, then halve. Peel outer layers from lemongrass until you get to tender core. Finely mince core. Pick and finely chop enough mint leaves to give you 1 TBSP.

Cut cucumber in half lengthwise, then slice into thin half-moons. Peel carrots, then cut into 3-inch lengths. Cut each length into thin wedges. Toss carrots on a baking sheet with a drizzle of oil and a pinch of salt and pepper. Roast in oven until lightly browned and tender, 15-20 minutes, tossing halfway through.

Meanwhile, in a small bowl, combine mayonnaise, a squeeze of lime juice, and up to half the sriracha (use less if you like it mild). Set aside.

In a medium bowl, combine pork, lemongrass, lime zest, shallot, 1 TBSP soy sauce (we sent more), half the mint, Thai seasoning, and remaining sriracha (to taste). Season with salt and pepper. Shape mixture into two evenly sized patties with your hands (they should be slightly wider than the buns).
