• 2 tbsp olive oil 
• 600g classic beef burgers 
• 4 slices cheese of choice 
• 1 onion, sliced into circles  

• 8 lettuce leaves 
• 2 tomatoes, sliced 
• 4-8 pickles 

• ½ cup mayonnaise 
• 1 tbsp pickle juice

1. Make the Sauce: In a small bowl, mix together mayonnaise, pickle juice, mustard, vinegar, tomato sauce, finely diced pickle, and a pinch of salt and pepper. Chill until ready to use. 
2. Cook the Onion: Heat 1 tbsp olive oil in a pan over medium heat and cook onion slices until soft and golden. Set aside.
