This is an idea, not an exact recipe.
We have always enjoyed a fish taco here and there, whenever we can get our hands on some reasonably priced, mild tasting white fish. This here ol' Capt' Steve caught himself. Bass, I believe.
Simply coat fish in a little olive oil, salt, pepper, and cumin. Spray a pan with cooking spray to minimize sticking and pan sear the little fishies.
For some added flavor, saute some peppers and onion. Other "toppings" : black beans, sour cream, lettuce, cheese, and homemade salsa.
Light, refreshing, and GOOD!
