In a bowl, combine all the meats, gently mixing so you don’t overmix. Shape and press into four burger patties, about 1/4 inch thick. Press a thumbprint indentation into each patty, and then season with salt and pepper.
Select Air Fry on the Vortex and adjust Temperature to 190°C and set Time to 9 minutes. Preheat Vortex until display indicates Add Food.
When prompted, lightly spray the patties and place them into the frying chamber, with the indented hole downwards.
When display indicates Turn Food, flip patties over and continue to cook until lightly browned and juices run clear when pierced. If you have a meat thermometer, then check the internal temperature reads 71°C.
Place cheese slice on top of each burger and place back into the Vortex. Select Reheat at 200°C for 2 minutes so the cheese starts to melt.
Meanwhile, in a small bowl, combine mayonnaise, ketchup and relish and mix well.
Once the burger and cheese is ready, assemble the burger by spreading the mayonnaise sauce inside of buns, place burger on bottom and garnish with toppings of your choice.
