Combine the flour, the eggs and the olive oil, and knead well.
Wrap the dough, and put in the fridge for 1 hour.
Thinly cut the prosciutto, and mix it with the parmesan and the chopped basil.
Roll the dough out the most finely possible.
Cut the dough in little squares (1.5 inches) using a pizza roll. Try to make the squares as perfect as you can.
Take a square of dough, and apply some water on the edges using your finger. Put a little bit of stuffing in the middle, and fold the square to form a triangle.
Fold once more, bringing the base of the triangle on its edge (as shown in the video). Then, take the 2 edges and stick them together in the middle.
Once all your tortellinis have been made, put them in boiling water for 5 minutes.
