Swai with Roasted Tomatoes and Onions

If ever there were a fish that I have found versatile, it is Swai.  It takes on the flavor of accompanying spices with such zest that it makes me love that fish.  I have even used Mrs. Dash on it with great results.  You can find it at your local Wal-Mart frozen section (it was a happy day when it appeared at mine.)
