Preheat the oven to 400 degrees, and line your baking sheet with Silpat, or spray with avocado oil spray, or lightly grease with butter or coconut oil.
Toss the cut up fish with the taco season and spread the pieces of coated fish onto the sheet pan. Bake for 10 minutes. If you made smaller pieces for little kids, you will have a shorter cook time.
Serve on your favorite tortillas with toppings of your choice!
