When it comes to convenience, nothing beats frozen fish. Imagine it’s the end of a long day, you haven’t planned dinner, and you want to cook something up quickly. Those well-packaged frozen fish fillets are your answer! They can be thawed easily, simply placed in a bowl of hot water (put the fish in a resealable plastic bag first) until the fillets can bend a bit. If you have a lean fish, such as cod or tilapia, you can put them directly in the pan or oven—no defrosting needed.
