Pre-heat oven to 350º.
Season salmon with kosher salt & pepper to taste, let rest for 5 minutes.
Lightly rub the salmon fillet with olive oil and sprinkle fennel pollen and mandarin zest on top.
Roast fish in the oven at 350º until the internal temperature of fish reaches 125º, about 10-12 minutes.
Prepare vinaigrette by combining shallots, honey, dijon mustard, mandarin juice, and sherry vinegar. Whisk in the olive and pistachio oils slowly to emulsify and season with salt & pepper to taste.
Cut endive & radicchio in half lengthwise keeping the stems intact. Rub the cut end with 1 Tsp of olive oil.
Char in a hot pan for 15 seconds. You’re looking to give it a bit of char, not cook it through.
Combine frisée, fennel, pistachios, mandarin segments, olives, and herbs into a bowl. Toss with vinaigrette just before serving reserving a tablespoonful of the vinaigrette.
Plate the salmon with the charred endive and radicchio, and spoon the salad over.
Drizzle a little extra dressing or olive oil on the plate around the salmon and enjoy!
