Start by draining the can of wild salmon. Use a fork to flake the salmon into smaller pieces, ensuring there are no large chunks.
In a mixing bowl, combine the flaked salmon, egg, seasoned panko, Frank's hot sauce, light mayo, Dijon mustard, and chopped scallions. Mix until all ingredients are well incorporated.
Spray the waffle maker with olive oil spray and preheat it according to the manufacturer's instructions.
Scoop about ΒΌ cup of the salmon mixture and form it into a cake. Repeat until all the mixture is used up, yielding about 4-6 cakes.
Place the formed cakes on the preheated waffle maker. Close the lid and cook for about 4-5 minutes or until golden brown and crispy on the outside.
Carefully remove the salmon cakes from the waffle maker. Serve hot with lemon wedges on the side.
