Let's start with cutting the buns in half (horizontally). Divide the crème fraîche on the two bottom parts.
Use a peeler to make thin long strips of cucumber. Then you can add the cucumber strips on top of the crème fraîche. I love to twist the cucumber strips a few times so they fit on the bun.
Then add the salmon, sprouts, a good amount of nacho's and the top of the bun.
Serve the sandwich with more nacho's or a salad on the side!
