My partner loved the vegies in this recipee he gave it a 5 plus I gave it a 3-4 , too many onions and I think I would have liked the fish (mahi, mahi) is what I used could have used some red pepper or something that would have given the fish a little more kick. Will fix it again.

My DH loved this, although I thought it was just OK. So I averaged it out to 4 stars. I couldn't find any grouper or sea trout, so I used Alaskan cod, which is a nice mild fish. Other than that I followed the recipe. Very easy, and even easier clean-up!
