Wash, dry, and slice the mushrooms.

Heat the butter in a pan. After a moment, add the mushrooms. Fry for a few minutes (2-4 min) until soft and the moisture has evaporated, stirring occasionally. Crack the eggs directly onto the pan. Gently and slowly stir.

When the eggs start to set (2-5 min), season to taste with a pinch of salt and pepper. Stir.

Transfer to a plate when the scrambled eggs reach the desired degree of doneness.
