Pickles:
In a medium bowl, mix together the cucumber, crushed red pepper, sugar, vinegar, soy sauce, and sesame oil.
Cover and refrigerate until ready to use.
Schnitzel:
Pour 1 ½ inches of oil into a large heavy pot or high-sided skillet. Clip on a deep-fry thermometer and heat the oil over medium-high heat to 360°F.
Set up a dredging station: Place the flour, eggs, and breadcrumbs in each of three separate bowls. Season the breadcrumbs with 1 teaspoon salt and a few turns of pepper.
Place a piece of chicken between two large pieces of plastic wrap and use a rolling pin or other blunt object to pound the chicken until it is as thin as you can make it without it tearing. Repeat with the remaining chicken.
Coat the chicken in flour, egg wash, and breadcrumbs and fry in batches, flipping once, until golden brown, 2 to 3 minutes. Transfer to a paper towel to drain and season both sides with salt and pepper and squeeze with lemon.
Assembly:1. Spread the insides of a bao with Sriracha mayo and fill with a piece of schnitzel and a few pickles.
