-first. Gather up all condiments that you put on a burger. For mine I'll be using ketchup, lettuce, pickles, and onion.
-second. Put all hard foods in bags and freeze them. Not the ketchup or mustard if you use them.
-third. Soak bun just a little bit with water and put in the freezer.
While the condiments are cooking cool the burger.
You can add cheese or not. I used American white cheddar cheese.
Blend them together anyway you want. ADD BUTTER!
