Here are some of my favorites. Easy.
Pan fried. Sleeve of saltine crackers and about half cup of flour in the food processor until crackers are small crumbs, not a powder. Toss in some seasonings too. I just dip the fillets in milk, but egg works for thicker breading. Usually season again after nice and golden brown, or darker. Ritz or Cheezits work well too.
Grilled. Coat both sides with mayo. I use light mayo, and works fin. I still use a fish spatula. Season to your taste, salt and pepper is just fine. Mayo will keep from sticking and give some incredible grill mark flavor. If you want to be fancy. Use different fish, with salmon and tuna in as well, to have different colors and flavors.
Baked or grilled. Look up recipes for both "Bourbon Chicken" and "Roadside Chicken" marinades. Works very well on fish too.
I like smoking fish too. A ton of good recipes on here that I have stolen in the past.
