Wash the salad and drain well. Mix vinegar, salt, pepper and some sugar. Stir in 1-2 tbsp. oil.
Squeeze the lemon. Mash goat cheese with a fork. Season with pepper. Peel and halve avocados and remove the stone. Brush the avocado all around with lemon juice. Season inside with salt and pepper.
Fill the goat's cheese into the halves and smooth it down.
Heat 1 tablespoon of oil in a coated frying pan. Fry the avocado halves in it with the cut surface facing down for 1-2 minutes until golden brown. Remove the pan from the heat. Carefully lift out and turn the halves.
Arrange salad on plates and drizzle with vinaigrette. Place 1/2 avocado on each plate. Freshly baked baguette tastes good with it.
