Bring a pan of salted water to the boil and cook the gnocchi according to packet instructions. Once cooked drain off and set aside. Season it well with salt and pepper.
Heat a large frying pan up over a medium heat and add in the walnuts to gently toast them, this should only take a few minutes, then remove and set aside. Add the olive oil and finely sliced garlic plus the sprigs of rosemary. Fry very gently for a couple of minutes being careful not to burn the garlic, otherwise it'll taste bitter, (the garlic should be very lightly golden and crisp, no darker), and infuse the oil with the aromatic flavours. Turn down the heat a little.
Remove the sprigs of rosemary and also the garlic pieces, reserving to use later and then add in the gnocchi. Fry the gnocchi until golden on each side, Tossing the pan occasionally to move them around so they don't catch. Once the gnocchi is lightly toasted and golden add in 2/3rds of the toasted walnuts plus 2 sprigs of the Rosemary, (after removing it from the stems and chopping it up finely). Re-add the crispy garlic pieces then toss everything together to incorporate.
Serve up, sprinkle over the remaining toasted walnuts and grate over some cheese. Garnish with a couple of rosemary sprigs if desired and drizzle over a little more extra virgin olive oil. Eat and enjoy! :)
