When I was little, my yiayia used to make what she called, Greek Fish. Sadly, I do not have her recipe. I do remember that she cooked whitefish in a tomato-based sauce, and it was delicious. Over the years, I have tried to recreate her recipe and I feel like the recipe I am going to share is the closest I have come. I rarely use theInstant Pot® for fish because it is an expensive ingredient and I would hate to waste it on a bad recipe. Now that I have had success with fish in the Instant Pot®, I plan to branch out and try more ideas.
