Preheat your oven to 350 degrees. Spray a cookie sheet with nonstick spray or line with parchment.
If cleaning your salmon, open the can and empty contents into a medium bowl. Clean away any skin or bones and transfer the cleaned fillet into a separate medium bowl.
If using already cleaned salmon, just drain away any water and empty the contents into the bowl.
Add the remaining ingredients, leaving the crackers or Parmesan cheese until last.
Divide the mixture as evenly as you can, making five or six balls. Transfer the balls to the cookie sheet and press them down until they are about 1/2 inch thick. Drizzle with a little olive oil (optional) before baking.
Bake until evenly browned, about 20-25 minutes. Serve warm.
