Let's start by making the Sweet Dijon. Combine all ingredients mentioned above in a small bowl and mix thoroughly. That's it !
Cut your fillet in 8 pieces and put it in a food processor. Press the grind button 4-5 times for about 3 seconds each time. Be careful, salmon is a delicate meat and it will turn into mush if you over work it.
Take your salmon out of the food processor, then add the egg, green onions, salt, and pepper. The texture should be very sticky.
At this point you want to start adding your bread crumbs slowly while mixing, until the mixture becomes thicker and malleable. If you need more bread crumbs go ahead and add some. Be careful not to put too much, you will end up with a dry bready burger.
Wet your hand lightly, and shape the patties.
Warm up a pan on medium heat, and cook on each side for 5-6 minutes or until golden brown.
While your patties are cooking place your buns in your oven and toast them. Make sure that only the inside is toasted.
Cut 4 Apple slices and remove core if needed.
Break your kale leaf into pieces that are the same size as your bun.
Stack up your burger in this order : Bread - little dollop of Sweet Dijon - Kale - Salmon Patty - Slice of Apple - Big dollop of Sweet Dijon - Bread. That's your map.
Serve and enjoy
