Preheat oven to 450°. Line a baking sheet with parchment or aluminum foil, and set aside.
In a food processor, combine bread, parsley, pistachios, garlic, olive oil, salt-free seasoning, ¼ teaspoon salt and pepper. Pulse until coarse crumbs form.
Place salmon on prepared sheet. Spread fillets with Dijon mustard. Sprinkle remaining ½ teaspoon salt on salmon, and press the bread crumb mixture onto all sides of the salmon. Make sure it sticks to the salmon.
Bake until the salmon is cooked & opaque throughout, 12 to 15 minutes. Enjoy!
