Banh mi-style veggie burgers

Banh mi literally translates to "bread" in Vietnamese, but it also refers to a sandwich filled with meat, herbs, and delicious pickled vegetables. This version utilizes traditional banh mi ingredients, but they're piled on top of soy burger patties instead. After marinating the carrots, radishes, and rice vinegar for a few minutes, they're incorporated with Boston lettuce leaves, kirby cucumbers, cilantro, and a punchy mayonnaise-Sriracha sauce for one of the most satisfying veggie burgers we've ever had. You can add a sliced hard-cooked egg to each sandwich if you want to up the protein punch. And feel free to use parsley or chives instead if you're not a fan of cilantro.
