Chop the onion and dice the sausage, then set aside.

Add butter to a pan over low heat. Add the chopped onion, sprinkle with salt and pepper, and sauté until the onion is soft and golden.

Add the sausage, sprinkle with paprika, and sauté until fragrant. Cook until the sausage and onion are slightly charred, then turn off the heat and let the mixture cool.

Place the ground beef in a mixing bowl. Once the mixture has cooled, add it to the bowl. Mix and knead until well combined and sticky.

Divide in half and shape into round balls. Place on plastic wrap.

Use your hands or a rolling pin to flatten into even thick sheets. Place cheese in the center, and use the plastic wrap to help roll the meat around the cheese into a log shape.

Shape into a log, ensuring the cheese is completely enclosed, including the ends. Wrap tightly with bacon. I used 2 slices of bacon to cover it completely. If needed, use more. Make another piece the same way.

Preheat the oven or air fryer to 250°F (120°C). While waiting, make the sauce by mixing all ingredients together. Place the sausage burgers on a baking tray and brush the outside with sauce (after baking, flip and brush the other side).

Once preheated, place the sausage burgers in the oven or air fryer for 20 minutes, then take them out, flip, and brush with sauce again. Bake for another 15 minutes.

Once done, serve on a plate. (I eat one piece at a time.) The crispy bacon wrapped around the fragrant burger and gooey cheese is delicious.
