On this particular evening, I made the patty as per the recipe then layered it in the lettuce bun with tomato, smashed avocado, [burger patty], gorgonzola, balsamic caramelised mushies/onions and baby spinach. With a side of Eggplant Chips.


For Burger Patties:

  • 400g organic mince of choice
  • 1 red onion, diced finely
  • 2 cloves garlic, crushed
  • salt and pepper to season
  • handful of fresh mixed herbs (I love parsley, mint and basil)

For the balsamic caramelised red onion (+ mushrooms):

  • 1 red onion, sliced
  • 1 clove garlic, crushed
  • 10 button mushrooms, sliced
  • 3 T balsamic vinegar

For the rest of the burger

  • Ice berg or fancy lettuce leaves, carefully peeled from the head – these will form the “bun” of your burger so you’ll probably need a couple of leaves folded together to encapsulate the burger.
  • sliced tomato for 4 people
  • organic cheese of choice if desired (I love gorgonzola)
  • Whatever other burger ingredients you may desire (pickles, mustard, mashed avo, spinach, cucumber, relish etc.)


  1. Place all burger patty ingredients in a bowl and combine together with your hands.
  2. Form into 4 burger patties and place on plate in the fridge so they can firm up a bit.
  3. Sautee onion, garlic and mushrooms in a pan for about 3 minutes until cooked down, add balsamic vinegar to caramelise and infuse flavour for 2 more minutes. Set aside until assembling burgers.
  4. Slice tomato, and other salad items for the burgers, prepare lettuce leaves.
  5. Take burger patties out of fridge and grill on a medium heated pan until cooked through.
  6. Assemble burgers in the lettuce leaves and devour!
