Quarter the tomatoes lengthways, as well as the strawberries. Put both in a bowl and mix together. Cut the basil leaves into fine strips.
Mix the other ingredients (it is important to choose a fruity balsamic vinegar as possible) into a dressing until it becomes creamy and mix with the strawberries and tomatoes. Sprinkle with basil.
This salad tastes very fruity and wonderfully sweet and sour. A nice refreshment for the summer.
