Directions

1. Heat broiler, with rack set 4 inches from heat. In a blender, combine cilantro, 2 tablespoons lime juice, 2 tablespoons oil, and 2 tablespoons water; season with salt and pepper. Blend until pureed. Set salsa aside.
2. In a small bowl, mix together remaining 2 tablespoons lime juice, remaining tablespoon oil, radishes, scallions, and jalapeno; season with salt and pepper. Set radish salad aside.
3. Place tilapia on a rimmed baking sheet; season with coriander, salt, and pepper. Broil until opaque throughout, 4 to 5 minutes; break up into chunks.
4. Meanwhile, using tongs, hold tortillas over a gas flame until lightly toasted, about 30 seconds per side (or wrap stacked tortillas in damp paper towels, and microwave on high until warm and soft, about 1 minute). To assemble, fill tortillas with fish and radish salad; top with salsa verde and fold.
