Get yourself a stovetop smoker. They are great for cooking for small batches when you don't want to drag out a big outdoor one. They work best on gas range tops, but they do work with electric as well.
I like a nice lemon-pepper smoked with oak, and a maple syrup and garlic smoked with cherry.
You can also do a seared cajun style if you have a good cast iron pan.
Or grilled with olive
oil, fresh basil. and a bit of lemon zest might be good for that specific fish.
Hope that helps,
Steve
