1 Season chicken breasts with salt and pepper, coat with mustard and sprinkle with breadcrumbs. Place the thyme sprigs in a small baking dish greased with 1 tablespoon oil. Place the chicken breasts on top and bake in a preheated oven at 180°C (approximately 350°F) for about 12 minutes.
2 Rinse the tomatoes, slice into quarters, remove seeds and cut into small cubes. Cut olives into slices. Peel shallots and dice finely.
3 Mix tomatoes with olives, shallot and parsley. Mix remaining oil with vinegar, season with salt and pepper and stir into the tomato mixture.
4 Arrange chicken breasts on plates and spread the tomato mixture over the chicken.
