Cheeseburger, mushrooms and avocado

In America we're big on double cheeseburgers, but what good is that when the meat patties are thin and there is extra bread in the middle? This is like that. Two childishly thin meat patties and the bread is too much for a sandwich like this. There is enough here to like, to pick at, to stab and combine, to push around and to fuss. 

It would be better if the cheese were a sauce.

It would be better broiled to finish.

It would be better with some kind of chile.
