If using 16 oz scallops, follow same instructions, cooking in batches if necessary, until scallops reach a minimum internal temperature of 145 degrees.
If using shrimp, follow same instructions as scallops in Steps 1 and 4, cooking undisturbed until seared on one side, 2-3 minutes. Flip, and cook until shrimp reaches minimum internal temperature, 1-2 minutes.
If using chicken breast, pat dry and cut into 1" dice. Season all over with a pinch of salt and pepper. Follow same instructions as scallops in Step 1, stirring occasionally until chicken reaches minimum internal temperature, 5-7 minutes.
If cooking without a protein, omit Step 4 and adding the scallops in Step 5.
