Air out the ground beef and add the egg, paprika, brown sugar, Worcestershire sauce, a dash of salt and pepper. Wash your hands and mix it all together.
Separate the large ball of beef and mould it into 4 separate balls.
Prep your board with flour so that the beef does not stick to your board or table while making the balls into burger patties.
Set aside your patties and start preparing the spinach and onions. In a pan, pour the bag of spinach with a bit of olive oil and a pinch of salt and steam it (closing the airflow with a lid) until it is fully cooked.
While the spinach is cooking, slice your onion in a way that keeps its rings.
Once the spinach is cooked, set it aside in a separate bowl and use the same pan (or you can use another one) to start heating the onions with a bit of butter or olive oil. As the onions take a bit of time to soften, you can also start cooking the patties simultaneously. Butter up the pan and start grilling!
Once the onions have softened and are yellow translucent, start marinating them with honey! I generally put around 3 tablespoons of honey per onion. Leave it on the stove until burgers are done.
While cooking your burger, place a slice of cheddar cheese on each patty until it is melted.
Start stacking up your burger! Cut up some tomatoes, too, for a fresh aspect to it!
