How to Make It
Make the vegetables Preheat the oven to 375°. On a large rimmed baking sheet, toss the beets, carrots and mushrooms with the olive oil and za’atar and season with salt and pepper. Roast for about 30 minutes, until the vegetables are tender. Immediately transfer the vegetables to a large bowl and fold in the bok choy until just wilted. Stir in the lemon juice and season with salt and pepper.
Meanwhile, make the charmoula In a food processor, combine everything except the salt and pepper and puree until nearly smooth. Scrape into a medium bowl and season with salt and pepper.
Make the salmon Season the fish with salt and black pepper. In a small bowl, whisk the ground coriander and cumin with the paprika and crushed red pepper. Season the salmon with the spice mixture.
In a large nonstick skillet, heat the olive oil until shimmering. Add the fish to the skillet skin side down and press gently with a spatula to flatten. Cook the fish over moderate heat until the skin is golden, about 4 minutes. Flip the fish and cook until medium within, about 3 minutes longer. Drain briefly on paper towels. Serve the fish with the vegetables and charmoula.
