Roast the slices of bread in a preheated oven (electric cooker: 225 °C/ gas: level 4) for about 5 minutes until golden brown. Take out and put aside. In the meantime, roast the pine nuts in a hot pan without fat until golden brown. Remove and set aside. Finely grate the Parmesan cheese. Peel and roughly chop the garlic.
Wash chervil and parsley, dab dry and pluck. Finely puree the herbs, pine nuts, Parmesan and garlic in a universal chopper, letting olive oil run in. Season with salt and pepper. Pour the pesto into a small bowl and set aside. Drain the mozzarella. Cut off the asparagus ends and peel the bottom 1/3. Cook the asparagus in boiling salted water for 5-8 minutes. Remove, rinse in cold water and dab dry. Wash the cherry tomatoes, dab dry and cut in half. Cut asparagus diagonally into bite-sized pieces. Mix asparagus, mozzarella, cherry tomatoes with 3/4 of the pesto. Cut bread slices diagonally in half and cover with 1 salad leaf each.
