Put in a tablespoon of salted butter in a pan and heat it till it melts
Chop up button mushrooms to a quarter and brown them up in the buttered hot pan. In a couple minutes u will notice the mushrooms will get a bit saucy due to the moisture in the mushroom and the butter
Add pepper and salt to taste to the sautéing mushrooms and wait till golden brown
Serve them up hot in a bowl. Yummy!
