- Vegetable oil cooking spray
- Four 6-to-7-inch corn tortillas
- 2 teaspoons extra-virgin olive oil
- 1/8 teaspoon kosher salt
- One 10-ounce halibut fillet, skinned and cut into 1/2-inch cubes
- 1/2 cup fresh lemon juice (from 2 large lemons)
- 1/4 cup fresh lime juice (from 3 to 4 large limes)
- Zest of 1 large lemon
- 1 teaspoon kosher salt
- 1/2 teaspoon freshly ground black pepper
- 2 tablespoons extra-virgin olive oil
- 2 tablespoons fresh lime juice (from 2 large limes)
- 1 teaspoon agave
- 1/4 teaspoon kosher salt
- 1/8 teaspoon freshly ground black pepper
- 3 green onions, pale green and white parts only, finely sliced
- 3 tomatoes, seeded and chopped into 1/2-inch pieces
- 1 large avocado, peeled, seeded and cut into 1/2-inch cubes
- 1 small jalapeno, finely diced
- 2 tablespoons chopped fresh flat-leaf parsley
For the tortilla chips: Place an oven rack in the center of the oven. Preheat the oven to 350 degrees F. Spray a small baking sheet with vegetable oil cooking spray. Set aside.
Using a pastry brush, brush the tortillas on both sides with the olive oil and sprinkle with the salt. Cut each tortilla into 8 triangles and arrange in a single layer on the prepared baking sheet. Bake until golden and crispy, about 15 minutes.
For the ceviche: In an 8-by-8-inch glass or ceramic baking dish, mix together the halibut, lemon juice, lime juice, lemon zest, salt and pepper. Cover the dish and refrigerate for 3 hours, stirring halfway through the refrigeration time to distribute the marinade.
For the salad: In a medium bowl, mix together the olive oil, lime juice, agave, salt and pepper until smooth. Add the green onions, tomatoes, avocado, jalapeno and parsley. Toss until coated.
To assemble: Divide the salad and spoon into 4 large martini glasses or 4 small salad bowls. Drain the ceviche and spoon on top of the salad. Garnish with tortilla chips before serving.
