Start by preparing the omelettes. In a bowl, combine eggs, cooked spinach and grated Grana Padano. Mix well, then season with salt and pepper.
Distribute the mixture in greased single-portion oven dishes. Cook in a preheated oven at 180°C for 20/30 minutes until the omelettes puff up.
In the meantime, in a bowl combine the salad leaves, peas and yellow tomatoes and dress with extra virgin olive oil, salt and pepper.
Serve the omelettes with the salad garnished with Grana Padano shavings, accompanied by the salmon on toast.
