Preheat oven to 350F. Bake chicken for 30 to 40 minutes, until juices run clear. Debone meat; keep warm. Heat 2 tablespoons walnut oil over medium heat; saute mushrooms and leeks quickly, about 1 minute. Remove from pan and keep warm. Divide the greens evenly among 6 plates. Add the citrus juices to the saute pan and reduce by 1/2. Remove from the heat and whisk in remaining walnut oil. Put chicken, leeks, mushrooms, grapefruit on greens; top with dressing and garnish with zest. Serve immediately.
