Preheat grill to medium heat.
Peel onion, leaving the core intact, as it will then be much easier to grill. Cut in half and quarter for a total of eight slices and coat with 2 teaspoons of olive oil.
Grill for five minutes per side or until charred.
Place on top grill for another 10 minutes until cooked through. Let cool and set aside.
Drizzle remaining olive oil over corn and grill for three minutes, turning frequently. Let cool and slice kernels off the cob.
Grill prawns for two minutes per side, or until the internal temperature reaches 165° F (74° C). Let cool.
Thinly slice broccoli florets and toss with onion, corn, prawns and remaining ingredients.
