Spread a baking paper on an oven tray.
Spread evenly all the meat mixture on the tray. Make a rectangular shape.
Standing on the wider side of the rectangular, place all the filling - eggs, carrots, potato and peas - in a line, in the middle. Leave some space to the sides.
Roll the opposite side to meet in the middle to form a log shape. Close the ends tight.
Turn the log over so the meeting line is facing downwards.
Spread the remaining egg white evenly all around the meat bowl with your hands or with an egg brush. This is done to reduce the risk of the log cracking up while cooking. If eventually the log cracks in some parts, do not worry, the taste will still be there.
Cook in a pre-heated oven at 160° Celsius for about 45 minutes.
Baste occasionally; take the stock that will occur in the oven tray with a spoon and spread it on top of the meat, so it does not get dry.
Rest for ten minutes after you take the meatloaf out of the oven. Cut to thick slices and serve while still warm with the sauce.
