Make a burger size of your mince. Cook it in the hot oil for 1mn per side in medium heat, reduce the heat to low-medium and cook an extra 1mn per side (for medium). Put the burger directly on the bottom-side, then the tomato, pickles, lettuce, onion and then the top-side bread. The classical burger has to be served with fried onion and French fries. Serve a nice cool (not chilled) light Californian red wine or a beer.
