Mix the eggs with the cream in a large bowl. Put the natural cornflakes crushed into small pieces in a large plate. Soak the slices of bread in the egg mixture and then bread with the cornflakes. Fry in a preheated frying pan with a stick of butter until golden.
Mix the Mascarpone, sugar, citrus zest and lime juice in a separate bowl. Stir well and serve with the breaded slices, Nutella, fruit and nuts.
