If using 16 oz. shrimp, follow same instructions as 8 oz. shrimp, cooking until shrimp reaches minimum internal temperature.
If using chicken breasts, pat dry and cut into 1" dice. Follow same instructions as shrimp in Steps 2 and 3, baking until chicken reaches minimum internal temperature, 18-22 minutes.
