Place fish, 1 tbsp. limejuice and black pepper in small bowl; stir well and let marinate at least 15 minutes, but not more than 30 minutes. Meanwhile, combine tomatoes, onion and garlic in medium bowl. Stir in serrano peppers; mix well. Spray medium nonstick skillet with cooking spray; heat over “high” heat. Add fish; cook and stir 2 to 3 minutes or until lightly browned. Reduce heat to medium; cover and cook for about 5 minutes stirring occasionally, or until fish begins to flake. Remove fish to clean bowl; set aside. Return skillet to medium heat; add tomato mixture. Cook and stir about 3 minutes or just until onions are soft. Return fish to skillet; cook and stir 2 minutes. Remove from heat. Add remaining 2 tbsp. limejuice and cilantro. Serve over rice and garnish.
