In a medium skillet over moderate heat, melt the butter. Add the green onions, spinach, and dill stirring occasionally, until spinach has wilted.
In a bowl whisk together the eggs, cream cheese , feta, dill, and pepper. Pour mixture over the spinach.
If scrambling the eggs, just stir until you reach desired texture of eggs and serve. Transfer to a serving plate and sprinkle with the chives or scallions.
OPTIONAL OMELETTE: (Make 2) Stir the eggs gently pushing the outer edges inward till the eggs begin to solidify. Leave it be for a minute or two but continue to shake pan a little to keep it loose from the pan.
When eggs are 2/3 of the way done, carefully 'flip' the pan with a quick jerk. If you don't know how to do that, you can slide the omelette onto a baking sheet and broil the top for a minute to continue cooking.
