Preheat the grill to approximately 400-425° F. Thread the shrimp and pineapple onto metal or wooden skewers (soak overnight if using wooden). Season with salt and pepper and brush or spray with oil.
Place the skewers on the grill and brush the tops with teriyaki sauce. Close the lid and grill for approximately 2 minutes. Flip the skewers over and brush with the remaining sauce and grill another 2 minutes or until just cooked through.
Remove from the grill and serve over quinoa, rice, or cauliflower rice. Garnish with sliced green onion, sesame seeds and the reserved teriyaki sauce.
