Combine this nutritious fish with south-of-the-border staples -- tortillas, cilantro, lime -- for an unexpected microwave meal.
Place salmon in a 2- to 2 1/2-quart shallow microwave-safe dish with a lid. Season with salt; drizzle with 1 tablespoon lime juice. Sprinkle with scallions and 1/4 cup cilantro. Cover, and microwave on high 7 minutes, until fish is cooked through. Pour off any liquid from dish; using a fork, flake fish.
Meanwhile, in a small bowl, stir together sour cream, remaining tablespoon lime juice, and remaining 3/4 cup cilantro. Season with salt and pepper.
Stack tortillas between 2 white paper towels. Microwave on high for 45 seconds, or until warmed through. Arrange lettuce and carrots down center of each tortilla; top with salmon. Drizzle lightly with sauce, and fold in half. Serve 2 tacos per person, with remaining sauce.
