In 10-inch skillet heat 1 teaspoon oil over medium-high heat; add carrot, zucchini, leek, and shallots and saute' until slightly tender, 3 to 4 minutes. Stir in remaining ingredients except fish and cook, stirring occasionally, for 2 minutes. Preheat oven to 375 degrees F. Using pastry brush, grease centers of two 15-inch-long sheets of foil with 1/2 teaspoon oil each; place a salmon steak on center of each sheet. Spoon half of vegetable mixture and liquid over each steak; fold foil over steaks to enclose, crimping edges to seal. Place foil packets on baking sheet and bake 15 to 20 minutes (until salmon flakes easily when tested with a fork and vegetables are tender). Carefully remove salmon and vegetables to serving plate.
