Beef and Egg Burger

Slice the tomatoes into 12 pieces. Slice the onions into rings. Cut the buns lengthwise and toast them cut-side down in a moderately hot pan until golden brown.

Place the bacon slices on a dry pan heated over medium heat, season with pepper and sprinkle with sweet paprika. Once golden brown on the bottom, flip them. Once golden brown on the other side, set them aside on a plate.

Form the meat into 4 patties the size of the buns and season them with salt and pepper on both sides. Place them in the pan with the leftover bacon fat and cook for 3 minutes over low heat. Then flip them and place 1 teaspoon of butter on each. Cook for another 2 minutes.
