Clean, wash and dry the chicken breasts. Cut it into strips or into smaller cubes, which you pepper and salt well in a bowl (you can use any spices you like).
Heat a little oil in a pan and fry the meat on each side. When the meat is fried, add cream cheese, finely chopped tomatoes, chili pepper, mushrooms and simmer everything together. Add milk, bouillon, which you have broken up in a little water and cook some more. When the meat is cooked, taste it, or season it, and you can serve it with pasta.
