Database driven menu that can be loaded in view

I have created a database driven menu using a Controller,

HomeController extends Controller which the menu is loaded in Controller's construct function.

HomeController.php

class HomeController extends Controller
{


    public function __construct()
    {
        parent::__construct();
        $this->middleware('auth');
    }

    public function index(){
        $data['menu'] = $this->menu;
        return view('home', $data);
    }
}

Controller.php

public function __construct()
    {
        $this->user = Auth::user();

        $menu = new Menu();

        if($this->user != NULL && $this->user != ""){
            $this->menu = $menu->getMenu($this->user->user_id);
        }   
    }

How can I, call the function straight at the view level because right now, even though the menu is loaded in the constructor, I will still need to pass the menu to the view which makes things a bit redundant.

P/S: Using laravel 5.1
