For the waffles, sift the flour, baking powder, salt and sugar into a bowl. Mix the egg yolks with the milk, oil, zest and vanilla seeds. Add the dry ingredients and mix well. Beat the egg whites until firm peaks form.
Fold gently through the flour mixture. Grease and preheat a waffle iron. Pour ½ cup of the batter into the waffle iron and cook for 4-5 minutes, until golden. Repeat with remaining batter. Serve with your favourite waffle topping.
For the caramelised pineapple, add the pineapple to a hot frying pan and cook over medium-high heat until tender and caramelised. Meanwhile, mix the rum, sugar, ginger and thyme. When the pineapple is ready, add to the rum mixture and leave to marinate for 2 minutes. Spoon over waffles and garnish with toasted coconut.
For the salad, mix the rockmelon, mango, mint, pistachios and lemon myrtle in a bowl. Drizzle with the honey and orange juice and turn to coat. Serve on top of waffles with coconut yoghurt.
