There's a shop in my neighborhood that has reliable frozen fried fish fillets, prepared in house. Nothing special, but they go in the oven and come out reliably crispy and tasty.
And a little bland.
I've done a few obvious things - lemon, soy sauce, sriracha, etc. But I was looking for ideas to dress these up. They're fast and reliable when I get home late, but I want to keep them interesting.
