Make any burger into a giant with the knowledge of extra patties at Jack in the Box. Essentially, for just a dollar per patty, you can stack as much beef as you want into a burger. At a certain point, they get a little too big for a normal human to eat, so try to order extras within reason.
At any rate, the ability to stack them as you please makes for a massive, filling burger at a fraction of the cost. Just ask for extras and they’ll load them up!
