SALMON WITH LENTILS AND MUSTARD-HERB BUTTER (SAUMON AUX LENTILLE

Steps:

• For mustard butter- stir together all ingredients with 1/4 teaspoons each of salt and pepper.
• Bring lentils, water, and 3/4 teaspoons salt to a boil in a heavy medium saucepan, then reduce heat and simmer, uncovered, until lentils are just tender, 20-25 minutes. Remove from heat and let stand 5 minutes. Reserve 1/2 cup cooking liquid, then drain lentils.
• While lentils cook, chop leeks, then wash. Cook leeks in butter in a heavy medium skillet over medium-low heat, stirring occasionally, until softened, 6-8 minutes.
• Add lentils with reserved cooking liquid to leeks along with 3 tablespoons mustard-herb butter and cook, stirring, until lentils are heated through and butter is melted. Add lemon juice and salt and pepper to taste. Remove from heat and keep warm, covered.
• Saute salmon while leeks cook. Pat salmon dry and sprinkle with 1/2 teaspoons salt and 1/4 teaspoons pepper. Heat butter in a large nonstick skillet over medium-high heat until foam subsides, then saute salmon turning once, until golden and just cooked through, 6-8 minutes total.
• Serve salmon, topped with remaining mustard-butter, over lentils.
