  1. Spray a barbecue plate or large griddle pan with oil and heat on high. Slice onion into 1-2 cm thick slices, keeping rings intact. Place on grill and cook for 4-5 minutes each side.
  2. Trim the mushroom stalk and place on the barbecue, stalk side down. Cook mushrooms 4-6 minutes then flip, season with pepper and cook mushrooms a further 2-4 minutes. Add cheese slice and cook for 2 more minutes until mushroom is cooked through and cheese is melted.
  3. Spray a large non-stick fry pan or flat barbeque plate with oil and heat over medium heat. Crack eggs carefully into the pan and cook until tops of white are set but yolks are still runny.
  4. Slice bread rolls in half and hollow out the tops to make more room for the fillings if you need. Lightly toast if desired.
  5. To assemble burgers, spread each roll base with chutney, add cooked onion slice, a cheesy mushroom and an egg. Fill each roll top with ¼ avocado then load up with tomato, pickles and lettuce. Carefully sandwich both roll halves together and secure with a wooden skewer. Serve immediately.


Other tasty burger additions: grilled pineapple, fresh or canned beetroot, sauerkraut or coleslaw.
