Step 1: Rinse your salmon in warm water, vinegar, and ½ a lime. This helps with the fishy smell and it makes your salmon absorb a nice flavor.
Step 2: Pat the salmon well with a paper towel and dry it. Then take a fork and lightly poke a few holes in it (only the front of the fish), and then season it with garlic powder, onion powder, and black pepper. Season it for 15 minutes.
Step 3: In a non stick skillet over medium heat add your oil. Make sure that the oil is hot before adding your salmon.
Step 4: Now add the salmon. Do not flip it! It will cook only on one side. Place a cover and let it cook for 5 - 6 minutes over medium-low heat
Step 4: Now add your teriyaki sauce over the salmon. Your sauce will thicken up quickly so you want to add ⅛ cup of water to make it less sticky and thick.
Step 5: Make sure you cover your salmon with the sauce. I typically take a spoon and pick up the sauce with it and add it to the salmon. You want your salmon to absorb flavor so I do this a few times. Let your salmon cook on low heat for 10 - 12 minutes.
Step 6: Feel free to add more water if the sauce gets thick. No more than 1 - 2 tbsp.
Step 7: Add chopped scallions and serve immediately.
