Peel and finely dice the onions. Clean, wash and quarter or halve the tomatoes as desired. Mix vinegar and mustard. Season to taste with salt, pepper and sugar. Wash chives, dab dry and cut into small rolls.
Stir onions and chives into the vinaigrette and add olive oil. Place the tomatoes in a bowl and pour the vinaigrette over them. Wash the meat, dab dry and cut into strips.
Whisk egg and cream. Crumble white bread very finely and mix with parmesan. Season parmesan breading with salt, pepper and paprika. Turn the meat first in the egg and then in the breadcrumb coating. Heat oil in a pan.
Fry the breaded meat in it in two portions over medium heat for four to five minutes while turning. Arrange the chicken sticks on a plate, garnished with parsley as desired, and add the tomato salad.
Paprika-filled olives and aioli taste great with it.
