Basically, these are ripe tomatoes sliced into wedges mixed with finely chopped onions, which are then topped with a sweet and sour dressing containing olive oil in a bowl. This salad is that quick to make!
Tomatoes ripen in the Czech Republic in August when they are sweetest and full of flavor thanks to the sun. That's why this salad is most often eaten in summer when it not only tastes delicious but also makes you feel fresh.
