Preheat your oven to 425°F. Arrange the frozen Beer Battered Cod filets on a baking sheet in a single layer. Bake for 16-18 minutes or until golden brown and crispy, turning halfway through.
Steam the bao buns according to package instructions.
Carefully open each steamed bao bun without tearing them. Spread a little sauce inside each bun. Add a few slices of radish, a small handful of shredded cabbage, and shredded carrots. Place a piece of the cooked Beer Battered Cod inside the bao bun.
Drizzle with additional sauce and garnish with green onion. Enjoy!
