Soak the black chickpeas overnight and cook them for about 2 hours with carrots, celery, and onion. Clean the shallot and cut it into julienne strips. Dice the bacon and brown it in a non-stick pan until crispy; drain it from the oil and brown the shallot in the oil. Add the black chickpeas and their cooking liquid to the shallot. Cook the tagliatelle and stir in the sauce and a little Parmesan cheese.
Roll up the tagliatelle and put them on the plate, garnishing them with the crispy bacon.
