In a bowl, mix together your mince, egg, breadcrumbs and seasoning.
Once everything is mixed well, divide the mixture into four and create the patties.
Place them into your air fryer and set them to 180°C for 10mins. Because the Vortex VersaZone lets you cook two different things at once, at different temperatures, I put chips into the other section of the air fryer (all 4 patties fit into one side) and set it to 180°C for 20min. I then made sure I used the SyncFinish option to make sure both the patties and chips finished cooking at the same time. Make sure to turn your patties and give your chips a toss half way through cooking. Once everything is cooked, place a slice of cheese on top of each of the burger patties and then let them cook for another minute.
You can now assemble your delicious burger and enjoy!
