Cut the mushrooms, carrots, onions and lettuce leaves into small cubes.
Heat a frying pan with vegetable oil. Fry the carrots and onions for 5 minutes, then add the mushrooms. Fry everything together for 10 minutes.
Add red beans, Chinese cabbage and tomato paste to the pan. Stir. Cook a little longer until the cabbage is soft.
Place the prepared filling on the tortilla and roll it up. The burrito is ready.
