We take the beans, I used dark red. Beans are well washed, it is better to soak overnight. Next, drain the water, pour fresh water in a ratio of 1 to 3, bring to a boil and cook over medium heat until ready, 1-1. 5 hours.
Mushrooms are washed, dried, cut into plates.
In a hot deep frying pan, pour half the amount of vegetable oil and fry the mushrooms over high heat until browned. Remove the mushrooms from the pan.
Peel the onions and carrots and cut them into small cubes.
In the same pan, add the oil and fry the carrots and onions until lightly golden.
