I often cook like that but pre-packaged fast-food is in fact faster to cook. I am not saying it should be eaten all the time, but the receipt you describe is not that fast. Mushrooms specifically are time consuming to clean in any non symbolic quantity.
And you also need rice/potato with it unless you go keto in which case you need much more cleaning/slicing mushrooms and more meat.
