Step by step recipe:

1. 3 min.
   Break 3 eggs into a large bowl, salt and pepper, then whisk to break them up.
2. 4 min.
   Pour 2 tablespoons olive oil into a small fryting pan on medium heat.
   
   When good and hot, pour in the beaten eggs and cook, drawing the edges in towards the middle.
   
   Stop as soon as the eggs are barely cooked. They should be scrambled but still soft and, above all, not too dry.
   
   Set aside to keep hot.
3. 4 min.
   Butter one side of 4 slices Sandwich bread.
4. 5 min.
   Lay the slices in a frying pan on high heat, butter side downwards and cook until the underside is nicely browned.
5. 5 min.
   Divide the scrambled egg between half the slices, add a tablespoon of pesto and top with grated Parmesan.
6. 3 min.
   Lay the remaining slices on top, turn off the heat and leave in the pan for another 2 or 3 minutes to heat everything through.
7. 
   Serve whole or cut in half diagonally.
