1. Melt butter in medium skillet over medium-low heat. Pour in eggs and let stand for a minute or two. Use a spatula to stir the eggs as curds start to form. When eggs look about 75 percent cooked, stir in cheese and remove from heat (the eggs will finish cooking from the pan’s residual heat). Season to taste with salt and pepper.
  2. Divide eggs among prepared avocado halves. Top with smoked salmon. Garnish with fresh herbs. Serve immediately.
