Preheat the oven to 425 degrees Fahrenheit.

Combine the oil and spices in a large bowl, then add fish and toss to coat. Place the fish on a baking sheet lined with Gefen Parchment Paper and bake uncovered for 15 to 20 minutes, until cooked through. Larger pieces may need more time, smaller pieces may need less.

Meanwhile, stir together the sauce ingredients.

Serve the fish in the tacos, piled high with toppings and drizzled with sauce.
