Made this tonight- and we loved it! I served it with rice and fresh steamed broccoli. There was PLENTY of sauce and it was pretty rich so you could easily use some lower fat versions of some ingredients and still have amazing flavor. I think this would work well for any light white fish. A new favorite for sure! Oh and I used a creole seasoning for the cajun seasoning and it was just right.
You probably guessed this already but the best part of all this is that the Parmesan gets a little crispy-crunch to it because it broils so beautifully. Pair that with the delicately flaky white fish and the fresh tang of the tomatoes, and then the thick and smooth basil sauciness of the pesto… ohhhyeah. I have a thing for texture. And cheese.
