Mix the ground meat with the spices, grated garlic and onion, salt and pepper.
Form two rather thin steaks.
In a frying pan over medium heat, put a teaspoon of vegetable oil and cook the steaks.
Cook for a few minutes on each side and set aside.
For The Caramelized Onions
Cut the onions into thin slices.
In a frying pan over low heat, pour a tablespoon of vegetable oil and add the onions.
Pour a little water and the teaspoon of honey. Cover and cook for 30 to 40 minutes, stirring occasionally. You can add water if necessary during cooking.
When the onions are brown and soft you can stop cooking and set aside.
For The Mayonnaise
In a bowl, pour an egg yolk and mustard. Mix well.
Then add the vinegar, salt and pepper and whisk well until the salt is completely dissolved.
Add a drizzle of oil and whisk well.
Pour the oil in very small quantities until the desired amount of mayonnaise is obtained (20 cl is just a general indication).
Whisk well all the way through so that the mayonnaise is nice and firm.
For the Coleslaw
Wash the carrot and cabbage. Peel the carrot and cut it and the cabbage into very thin slices.
Mix the carrot and cabbage slices with one to two tablespoons of mayonnaise. Set aside.
To assemble the Burger
Just before assembling your burger, put your steaks back in the pan over low heat and put two slices of cheese on each steak to melt them by covering the pan with a lid.
Spread the Burger Sauce generously over the base of the burger bun. Then place two slices of tomato and a lettuce leaf.
Then place a first steak and its melted cheese, then again two slices of tomato, a tablespoon of coleslaw, then the second steak and its cheese and finally a nice tablespoon of caramelized onions.
On the top of the burger bun, spread one or two tablespoons of Burger Sauce.
You can hold it all together with a wooden skewer.
Finally, sit down at the table, bring one or two paper napkins, and ... BITE!
