Another very simple way in which to cook mushrooms is to stew them and then serve them on toast. When prepared by this method, both the stems and the caps are utilized.
Clean the mushrooms and cut both the caps and the stems into small pieces. Cook until tender in sufficient water, stock, or milk to cover them well, and then season with salt and pepper. To the liquid that remains, add enough flour to thicken it slightly. Serve on toast.
