The original recipe called for tilapia. However, we are huge fans of ono lately, so I used that instead. It was very good. I think in this instance though, the tilapia might have been even better. My husband insists that it was perfect as is, but I’m still thinking that tilapia would have been better. A more delicate fish might have been even more perfect with that amazing sauce. And this meal was most definitely all about the sauce!
