Preheat the oven to 180C.
Roast the capsicum in the oven until the skin is burnt and blistered. Set aside in a plastic bag until its cool enough to remove the skin and seeds.
While the capsicum is roasting fry the onion in the olive oil until golden and slightly crispy (approx 10 minutes).
Blanch the silverbeet in boiling water for 2 minutes then drain and set aside.
Combine the silverbeet with the ricotta and cornichons and season with black pepper and a pinch of sea salt.
Separate the egg whites and beat until they form stiff peaks. Beat the egg yolks in a separate bowl then fold them into the egg white mixture. Lightly grease a 22cm round cake tin. Pour ½ the egg mixture into the bottom of the dish then layer the onions and capsicum over the surface. Spread the spinach and ricotta mixture and then top with the remaining egg.
Cook in the centre of the oven for 20 - 25 minutes.
Serve with fresh asparagus or a green salad.
TIP: Egg shell is porous and will absorb smells and flavour from other refrigerated foods. Always store them in a covered section of the fridge or in their cardboard boxes.
