I saw a similar recipe on an Italian Magazine (Sale & Pepe), but I changed a lot from the original concept, so I can say : this is my Kale Bundles over cheese fondue.
Start making a normal egg-dough for tagliatelle (1 egg every 3 oz of flour)
Than using the pasta maker or a pin-roll make 8 lasagna squares 5" by 5"
they have to be very thin: once boiled for 3 minutes they should be transparent
Now pick some green onions (trimmed and washed) and take 8 of the external layers and blanch them for few seconds in boiling water
At this point put some kale leaves (trimmed and washed) in a pan, sauteing them with some sliced onion in a little oil until cooked, but still firm.
Once no more warm, puree them with some ricotta cheese and pecorino romano, with a generous pinch of grated nutmeg
and fill a sac-a-poche with the creamy Kale paste
