Martha’s Fish Tacos

Directions

1. Spread corn with butter and sprinkle with salt and pepper. Grill, covered, over medium heat until tender, 10-12 minutes, turning occasionally.
2. Meanwhile, sprinkle fish with 1 teaspoon chili powder. On a lightly oiled grill rack, grill fish, covered, over medium heat until fish flakes easily with a fork, 7-9 minutes.
3. Cool corn slightly; remove kernels from cobs. Place in a large bowl. Add the lettuce, tomatoes, red pepper, avocado, taco sauce, 1 tablespoon lime juice, cilantro, lime zest and the remaining chili powder.
4. Drizzle remaining lime juice over fish; cut into 1/2-in. cubes.
5. Add fish to corn mixture. Spoon 1/2 cup mixture over each tortilla. Serve immediately.
