How to Make It
Combine the first 5 ingredients in a medium bowl; stir in 1/4 teaspoon salt.
Heat a large nonstick skillet over medium-high heat. Coat pan with cooking spray. Sprinkle remaining 1/4 teaspoon salt and black pepper over fish. Add fish to pan; cook 4 minutes on each side or until fish flakes easily when tested with a fork or until desired degree of doneness. Place 1 fillet in each of 4 shallow bowls, and top each serving with 1/2 cup cucumber salad and 1 teaspoon peanuts.
