In a medium bowl, flake the cooked wild-caught salmon into small pieces using a fork.
Add the egg white, almond flour, 1 tablespoon of Greek yogurt, finely diced celery, red onion, fresh dill, lemon zest, sea salt, and black pepper to the salmon.
Mix the ingredients thoroughly until well combined, then form the mixture into two or three evenly sized patties.
Heat the olive oil in a non-stick skillet over medium heat.
Place the salmon cakes in the skillet and sear for 4-5 minutes per side until they are golden brown and crispy.
While the cakes are cooking, whisk together the remaining 2 tablespoons of Greek yogurt, lemon juice, Dijon mustard, and garlic powder in a small bowl to create the aioli.
Serve the warm salmon cakes immediately with a dollop of the zesty aioli on top.
