Start by browning diced onions in a pan over medium-high heat, once cooked set aside.
Spray your pan with light cooking oil & add extra lean beef mince, smash using a spatula and leave it for a few minutes to develop a crust. Flip & repeat for the other side.
Once the meat has browned & developed a crust on each side break it apart & add mustard, ketchup, Worcestershire sauce, light mayonnaise, garlic powder, pepper, smoked paprika, diced pickles (optional), light cream cheese & continue stirring until creamy & smooth.
Now make the special burger sauce by mixing all the sauce ingredients together listed above in a bowl then transfer to a squeeze bottle.
Assemble each quesadilla: Place a warm tortilla down, sprinkle a layer of light cheddar cheese, equally distribute the filling followed by a portion of the cooked onions, drizzle of the sauce, another layer of cheese & fold over.
Toast using a pan on each side until golden brown & crispy, then repeat for the remaining 9 quesadillas.
