Wash and clean the salad and drain thoroughly. Drain palm hearts. Roast pine nuts in a pan without fat until golden brown, remove and let cool. In the meantime wash and halve the tomatoes.
Cut palm hearts and salad into pieces. Halve the avocado, remove the stone and remove the flesh with a spoon. Quarter the flesh if necessary and cut into slices. Put prepared ingredients in a bowl.
Season vinegar with salt, pepper and sugar, fold in oil. Carefully fold in the vinaigrette. Baguette tastes good with it.
