First, grill the fish fillets; or cook it however you choose.
Prep all your fresh ingredients. Wash and chop the lettuce, tomatoes, and green onions. Also, shred the cheese.
Fry up a batch of corn tortillas to form taco shells. You can use bacon grease or canola oil.
Once the fish is fully cooked, taco shells are done, and fresh ingredients are prepped, you’re ready to start the process of layering. You can layer ingredients in any order you want.
Add the fish into the taco shell first, then the cheese.
Layer lettuce, a layer of tomatoes, green onions, and whatever else your heart desires.
Add a dollop of tzatziki sauce or sour cream to top them off.
