Beat 2 eggs and 2 tablespoons of mineral water. Season with salt and pepper. Heat 1 teaspoon of oil in a coated pan (20 cm Ø) and pour in the egg mixture. Leave to falter slightly over medium heat. Sprinkle 1 tablespoon of Parmesan cheese over it and let it falter further.
Slide the omelette onto a plate or flat pan lid. Fry from the other side for another 2 minutes. Remove and bake another 3 omelettes in the same way. Spread 2 omelettes with 3 tablespoons of green pesto each and cover with 3 slices of Parma ham. Roll up the omelettes and cut them diagonally into 5 pieces. Drain the mozzarella and cut into thin slices. Wash the basil and, except for something to garnish, pluck the leaves from the stalks. Spread 2 omelettes with red pesto, cover with mozzarella and basil. Roll up and cut into pieces.
