Prep the salmon. After the skin is removed from the salmon, cut the salmon into chunks. Then, hand chop it with a chef's knife for a minced chop, with a few larger bits remaining for texture.
Mix. Add the salmon, egg, almond flour, red onion, parsley, garlic, mustard, lemon juice, salt and pepper to a mixing bowl. Gently mix until just combined (try not to overwork it).
Form and chill. Shape the mixture into 4 patties. Then refrigerate the patties for 20 to 30 minutes (this helps them hold together).
Cook in a pan: Heat the oil in a skillet over medium heat. Cook 3 to 4 minutes per side, until golden and just cooked through. Cook on a grill: Alternatively, cook them for 4 to 5 minutes per side on a grill. Note: These are slightly more fragile on an outdoor grill. See my extra tips in the post above to prevent breakage.
