Grilling Temperature For Fish

What is the best way to cook frozen catfish fillets?
I know that is not frozen is as good as fresh, but a student who does not fish (I do not know how to clean and fillet). Therefore, this method of cooking and seasoning should I use? In addition, there Would sauces that go well? As for the methods cooking, I should mention that I have never grilled (do not know how to use the girll). So, maybe the grid is not the best option. I really hope that someone with experience can help me. I'm usually not much in the kitchen because I lack the intuition for this. Also, if a list of instructions for cooking the recipe /, please be as detailed as possible (like, tell me what brands you buy things, temperatures and exact times for cooking accurate, non-technical, etc) Thanks!
Thaw them, seasoned with spices and make a mixture of beer and fried. Serve with Red Pepper sauce as roas or tartar sauce.
