Whisk together 2 tablespoons chives, eggs, sour cream, and mustard in a large bowl.
Melt butter in a large oven-proof skillet over medium heat. Reduce heat to low; add egg mixture. As egg mixture starts to cook, gently lift edges with a spatula and tilt pan so uncooked portion flows underneath. Cook 6 to 8 minutes or until uncooked egg mixture no longer flows underneath cooked mixture. Remove from heat. Sprinkle with salmon, cream cheese, and onion.
Broil frittata, 3 inches from heat, 3 minutes or until set and cream cheese begins to melt. Remove from oven, and sprinkle with remaining chives. Cut into wedges, and serve immediately.

This recipe is in desperate need of revision.
