I made this soon after this recipe came out in Bon Appetit. The photos in the magazine were just gorgeous. My guests especially loved the pistachio pistou. It had a great texture and saltiness that went well with the fish. I highly recommend this recipe. We get our salmon at Costco and can't say enough about how awesome the frozen salmon at Costco actually is. The pieces are large, fresh and very flaky. Otherwise, Whole Foods is the best option.
1/3 cup chopped fresh dill 1/3 cup finely chopped green onions (about 2) 1/2 cup shelled natural pistachios or almonds, toasted, finely chopped 1/4 cup plus 1 1/2 tablespoons pistachio oil or extra-virgin olive oil 2 yellow bell peppers or orange bell peppers, cut into 1/2-inch strips 1 pound sugar snap peas, trimmed, strings removed 1 garlic clove, minced 1/4 cup water 4 6-ounce salmon fillets
Mix dill, green onions, pistachios, and 1/4 cup oil in medium bowl. Season to taste with salt and pepper. DO AHEAD: Pistou can be made 2 hours ahead. Let stand at room temperature.
Heat 1/2 tablespoon oil in heavy large skillet over medium-high heat. Add peppers and sauté until beginning to soften, about 2 minutes. Add snap peas, garlic, and 1/4 cup water; sprinkle with salt. Sauté until vegetables are just tender and water evaporates, 2 to 3 minutes. Stir in 1 rounded tablespoon pistou. Transfer vegetables to platter; tent with foil to keep warm. Reserve skillet (do not clean).
Heat remaining 1 tablespoon oil in reserved skillet over medium-high heat. Sprinkle salmon with salt and pepper. Place salmon, skin side down, in skillet; cook until skin is crisp, about 3 minutes. Turn salmon and cook until almost opaque in center, about 3 minutes longer. Arrange salmon fillets over vegetables on platter. Spoon some pistou down center of each fillet and serve, passing remaining pistou alongside.
