I did tilapia in black bean and garlic sauce last weekend - it was wonderful. I cooked a whole (not fileted) fish and liberally coated it inside and out with the jarred - yes, jarred sauce from the Asian market - and baked it at 350 until flaky.
Served with white rice and a side of veggies.
I hate grilling fish because, well, I just don't do it well, so I have learned that with salmon and tilapia you can season them with whatever and bake them. If you leave the skin on put it skin up and uncover during the last part of cooking so it crisps. Or you can cheat, like I do, and toss it under the broiler for a quick crisp.
A nice salad, or mixed fresh steamed veggies, and a starch and you have a lovely meal.
Enjoy.
