Follow these simple steps to create your delicious Greek Tzatziki Fish Tacos:

1. Prepare the Fish: Pat the fish fillets dry with paper towels. Cut them into bite-sized pieces.
2. Set Up Breading Station: In three separate shallow bowls, place the flour, beaten eggs, and panko breadcrumbs mixed with garlic powder, paprika, salt, and pepper.
3. Bread the Fish: Dredge each piece of fish in the flour, shaking off excess. Dip it into the beaten eggs, and then coat it with panko breadcrumbs, pressing gently to adhere.
4. Heat Oil: In a large skillet, heat olive oil over medium heat.
5. Cook the Fish: Once the oil is hot, add the breaded fish in batches. Cook for 3-4 minutes on each side until golden brown and cooked through. Remove from the skillet and place on a paper towel-lined plate to drain excess oil.
6. Warm Tortillas: In a separate skillet, warm the tortillas over low heat for about 30 seconds on each side, or until pliable.
7. Assemble Tacos: On each tortilla, layer the cooked fish, a generous dollop of tzatziki sauce, shredded lettuce, diced tomatoes, and sliced red onion.
8. Garnish: Squeeze fresh lemon juice over the tacos for added flavor.
9. Serve Immediately: Enjoy the tacos warm for the best taste and texture.

These steps will guide you in creating Greek Tzatziki Fish Tacos that will impress everyone at your table.
