Notes
Use wild shrimp when possible. It is healthier for you and just tastes better. Frozen shrimp works fine too but just make sure they're thawed before cooking.
If you use pre-cooked shrimp, you want to cook just 30 seconds per side so they don't get overcooked.
If you don't have fresh ginger, replace with ½ teaspoon of dried ginger.
If you like some heat, add ¼ to ½ teaspoon crushed red pepper flakes.
Wait until teriyaki sauce has thickened before adding the shrimp.
