Soak beans in plenty of water overnight. Then boil until cooked (add salt 20 minutes before the end of cooking), drain the water. Drizzle with good olive oil.
Cut the chicken fillet into cubes and marinate in soy sauce for 30 minutes.
Peel the mushrooms and quickly fry in a very preheated skillet (so as not to lose their juiciness).
Fry fillet pieces for 5 minutes until lightly blush, do not dry out! Combine all the ingredients and serve the salad warm!
