Balmain Bugs or Moreton Bay Bugs are found in Queensland, their flesh is much more 
tender than shellfish (like small crabs)

8 green balmain bugs
  salt
2 mangoes, peeled and chopped
3 tablespoons sour cream
¼ cup lemon juice
1 teaspoon brown sugar
2 teaspoons sweet chilli sauce

Bring a large pot of water to the boil. 
Add some salt. Place bugs in the water, simmer uncovered for 5 minutes, until shells have 
 an orange colour. Carefully separate the heads from the bodies with scissors. 
Cut along the underside of the bug and gently remove the meat. 
To prepare mango sauce, place all remaining ingredients into a food processor, process 
 for 20 seconds or until smooth. 
Place bugs on individual plates. 
Heat sauce and pour over the bugs.
