For the Sauce:

  • 2 avocados
  • 1/4 cup cilantro
  • 1 tablespoon lime juice
  • 1 teaspoon lime zest
  • ¼ tsp salt

For the Fish:

  • ¼ cup cornmeal
  • 1 tablespoon chili powder
  • 1 teaspoon cumin
  • 1 teaspoon dried oregano
  • 3/4 teaspoon salt
  • 1/2 teaspoon garlic powder
  • 1/2 teaspoon onion powder
  • 1/8 teaspoon cayenne pepper
  • 5 5-6 ounce tilapia filets thawed if frozen
  • 2 tablespoons vegetable oil
  • 5 sub or hamburger buns
  • 2 ripe tomatoes thinly sliced
  • 5-10 lettuce leaves separated, washed, and patted dry


  • Place all of the sauce ingredients into the bowl of a food processor and process until smooth. Transfer to a small bowl and chill until ready to assemble the sandwiches.
  • Combine cornmeal, chili powder, cumin, oregano, salt, garlic powder, onion powder, and cayenne in a wide, shallow bowl. Carefully pat dry each tilapia filet and dredge one at a time in the cornmeal mixture, making sure to completely cover each filet. Set aside on a clean plate.
  • Heat the vegetable oil in a large sauté pan on medium-high heat. As soon as it’s hot, pan fry the fish 4-5 minutes on each side. Cook in batches if necessary to avoid overcrowding the pan. The fish will flake easily when done.
  • Once the fish is cooked, assemble sandwiches by placing a filet on each bun, then topping with lettuce, tomato, and the prepared avocado lime sauce.


Lightly brush the buns with butter and toast for another layer of flavor and crunch.
