In a large bowl, combine the flaked salmon, breadcrumbs, mayonnaise, green onions, and mustard.
Add the beaten egg and mix until well incorporated.
Season the mixture with garlic powder, salt, and pepper.
Form the mixture into patties, roughly 2 inches in diameter.
Heat oil in a skillet over medium heat.
Once hot, carefully add the salmon cakes to the skillet.
Cook for about 4-5 minutes on each side until golden brown.
Remove from the skillet and place on paper towels to drain excess oil.
Serve warm with your choice of dipping sauce.
Enjoy your delicious salmon cakes!
