Finely chop the onion. Cut the snap peas into small pieces. Remove the stems from the mushrooms and slice thinly. Slice the beef into large, thin pieces.

Melt the butter in a frying pan, then add the onion and sauté.

When the onion is lightly browned, add the beef to the pan.

Once the beef is cooked, add the mushrooms and snap peas to the pan and sauté. Season lightly with salt and pepper.

Dissolve the bouillon cube in a little hot water, then add it and the cooked rice to the pan. Stir-fry to make pilaf. Transfer to a plate.
