The original recipe called for halibut, but mahi-mahi was cheaper at Costco and it sounded better to me. I also subbed a variety of sweet peppers for the red peppers. I bought the bag of sweet peppers at Costco. I think they added better color and flavor. I also decreased the amount of jalepeno and it still had enough kick and used lime instead of lemon. Other than that, I followed the recipe.
