Place onion, parsley and garlic in the bowl of food processor and pulse until minced.
If your salmon has skin, use a sharp knife and carefully cut the salmon meat from the skin and place into bowl of food processor. Discard skin.
Pulse a few times and then add in the eft of the ingredients and pulse until combined.
If you have the time, scrape the mixture into a bowl and allow it to chill for 30 minutes or so so the flavors mingle and the mixture sets.
When ready to cook, form a very small patty and cook it off to taste, this wat if you need more seasoning you can adjust the mixture before you form into balls (something I always recommend when making meatballs, burgers, meatloaf etc).
Form the mixture into balls, like you would a traditional meatball. Pressing firmly to compact each ball as you would a snowball to help it hold its shape.
Heat just enough oil in a large pan/skillet to just coat the bottom. Once hot, add the salmon balls without crowding.
Cook for about 5-7 minutes, flipping them halfway through. Cook time will depend on your preference for doneness as well as size of balls.
Once the salmon balls are golden brown and cooked to your liking, remove them from the skillet and serve enjoy as is, with tarter sauce, a lemon cream sauce or on a roll banh mi style.
