I was so against fish taco's to me it just sounds gross. But I found a recipe and started making them and just love them.
Here is my recipe sorry it is kind of a by memory recipe.
White Fish, I have used Flounder and Tilapia
Veggies of your choice
Rice on the side
I put the fish in rice in my rice cooker and it cooks in about 25 minutes and is so good. Season the Fish with Blacken Seasoning. I would saute the veggies separately. As for the Ranch dressing I make it with 1/2 cup light mayo and 1/2 cup greek yogurt, onion powder, garlic powder, parsley, pepper. This makes a really good little sauce. When the fish and everything is cooked put inside warm corn tortillas.
