Put all ingredients for mulled wine sauce in a small saucepan. Bring it to a boil, then reduce heat and let it simmer for 30 minutes.
Use an immerse blender or a regular blender to thicken the sauce. You don't need to make it completely smooth.
Divide minced beef into 4 and make patties that are slightly larger than the bun.
Heat a pan and add a tablespoon of oil. Fry the patties for about 4 minutes on one side. Turn around, season with salt and pepper and cover with slices of cheddar. Cook for another 4 minutes for a medium burger or for 5-6 minutes for a well done. Cover with lid if the cheese needs some help with melting.
Cut the buns in half, spread the mulled wine sauce on the bottom part, add the burger patty, top with arugula and slices of oranges. Cover the burgers and enjoy!
