Chicken fillet, in this case baked chicken breast, in cubes.
If the onion is large, then cut into half rings. Small rings. Cherry tomatoes in halves. Onions, if too angry, scald with boiling water or marinate in a mixture of water-vinegar 1:1 and a pinch of sugar for 20 minutes.
Put the components of the salad in serving glasses at random
For the dressing, mix the vegetable oil with mustard, lemon juice, soy sauce, beat with a whisk, adjust the taste with sugar (I use honey)
Pour the dressing over the salad, sprinkle with grated cheese on a fine grater.
