Peel or wash the onions and tomatoes and cut into cubes. Spread in a baking dish. Squeeze in the clove of garlic and mix. Season everything with salt, pepper and basil. Place the fried chicken breasts on the tomato bed. Cut the salmon into very small pieces and spread over the chicken breasts. Cover everything neatly with grated parmesan.
Bake in a preheated oven at 180 ° C for approx. 20 minutes.
In the case of food combining, serve without a side dish, otherwise add croquettes or bread.
