Preheat oven to 400 degrees F. Line a baking sheet with parchment paper.
Make green chile sauce. In a food processor, combine parsley, jalapenos, preserved lemon, garlic, olive oil, lemon juice, salt, coriander, and black pepper. Pulse until mixture is finely chopped and resembles a paste.
Place salmon on prepared baking sheet and spread green chile sauce on top in an even layer. Roast for 12 minutes. Turn on the broiler on high and broil for 3 minutes or until lightly charred. Remove from oven.
While salmon is cooking, make tahini sauce. Blend together tahini with water, lemon juice, garlic, and salt until smooth. Stir in Greek yogurt and mix until well combined.
Spoon tahini yogurt sauce on serving platter and place salmon on top. Sprinkle breadcrumbs on top and serve immediately.
