Using a sharp knife coarsely chop salmon to a sausage like texture (approx. 1/4-inch pieces).
This can also be done in a 3 batches in quick bursts in a food processor. Or use canned salmon if in a rush.
In a large mixing bowl stir together 1/4 cup panko bread crumbs (or ground pork rinds), parsley, green onions, garlic, mayonnaise, lemon zest, dijon mustard, old bay seasoning, egg yolk, 1/2 tsp salt (or to taste) and 1/4 tsp pepper.
Add salmon then toss well to evenly coat with mixture.
Scoop mixture 1/3 cup at a time creating 8 equal portions.
Pour remaining 3/4 cup panko (or pork rinds) into a shallow dish.
Press and shape portions into 3-inch patties then coat and gently press into panko (or pork rinds), coating both sides.
Pour 3 Tbsp oil (or butter) into a large non-stick skillet and heat to medium-high heat.
Add four salmon patties (if needed carefully tilt pan for oil to run under salmon if it isn't already). Let fry until golden brown on bottom, about 2 minutes.
Carefully flip and continue to cook until second side is golden brown and patties are just cooked through, about 2 minutes longer.
Let drain on paper towels then repeat with repeat process with remaining four salmon patties.
