Inexpensive tilapia is readily available and sustainable. Broiling makes this a no-fuss fish dish. The tilapia cooks fast, so make sure all the other components for the taco are ready before you put it under the heat.
1. Preheat broiler to high.
2. Combine first 4 ingredients and 1/4 teaspoon salt. Brush fillets with oil, and sprinkle with spice mixture. Place fillets on a baking sheet. Broil 6 minutes or until fish flakes easily when tested with a fork.
3. Combine remaining 1/8 teaspoon salt, cilantro, chiles, and avocado in a bowl; lightly mash with a fork.
4. Heat tortillas on a grill pan coated with cooking spray 20 seconds on each side or until lightly charred. Divide avocado mixture and fish among tortillas. Serve with lime wedges.
