Saute the onions and garlic in a large frying pan over medium heat until soft and caramelized, about 15 minutes.
In a bowl combine:
Scallions (chopped finely into ringlets), ginger (ground finely on a cheese grater or lemon zester), soy sauce, sesame oil, chili and garlic sauce, meat, and the sauteed onion and garlic. You can add a dash of white wine vinegar if you're feeling adventurous.
Mush together with your hands until ingredients are fully combined. Form into patties. Cook and serve however you normally would for a hamburger or cheeseburger - you can add cheese and ketchup, serve with lettuce and tomatoes, it's fully customizable.
