Pass values between monobehaviour classes

Unity Engine

How can I pass values from one MonoBehaviour class to another MonoBehaviour class using the current instance of the class (GameController in this example) without using static methods/variables? Thank you very much!

public class GameController : MonoBehaviour
{
    public string midFilePath;
    void FromMenu (string path)
    {
        midFilePath = path;
    }
}

public class Menu : MonoBehaviour
{
    string path = "";
    void OnGUI()
    {
        path = GUI.TextField(new Rect(80, 20, 600, 30), path, 255);
        if (GUI.Button (new Rect (20, 20, 50, 30), "Load"))
            //How to make GameController.midFilePath = Menu.path?
    }
}
