Shrimp: Add shrimp in a single layer (do in two batches if needed). Cook 2-3 minutes per side until pink and opaque. Use your spatula to flip.
Serve & Store: Remove from heat. Stir in lemon juice, zest, and parsley. Serve half the shrimp over rice. Store the other half (about 1 lb) in an airtight container for Friday's Fried Rice.
