Prepare the necessary ingredients.
Wash the mushrooms, slice them and put them on a frying pan with vegetable oil. Fry for 10-15 minutes until cooked. The mushrooms will become soft and brown. Do not cover with a lid during frying to allow the liquid released from the mushrooms to evaporate. Transfer the mushrooms to a plate.

Peel and finely chop the onion, then sauté it for a couple of minutes in the frying pan.
1 pcs yellow onion
Add grated carrot to the frying pan.
