1. Sprinkle fish evenly with pepper and salt. Place flour in a shallow dish; dredge fish in flour. Heat a large nonstick skillet over medium-high heat. Add 1 tablespoon oil to pan; swirl to coat. Add fish to pan; cook 3 minutes on each side or until fish flakes easily with a fork. Remove fish from pan; keep warm.
2. Return pan to medium heat. Add butter; cook 45 seconds or until butter begins to brown. Remove pan from heat; stir in parsley and 1 tablespoon lemon juice. Place butter mixture in a small bowl.
3. Return pan to medium-high heat. Add remaining 1 teaspoon oil to pan; swirl to coat. Add snap peas; sauté 3 minutes or just until crisp-tender. Stir in remaining 2 teaspoons lemon juice, mint, and rind. Drizzle browned butter mixture evenly over fish. Serve with snap peas.
