Whisk the 00 flour, semolina and salt together in a medium-sized bowl. Pour the mixture onto a clean, cool counter top. Make a well in the center of the mixture.
Place 2 of the eggs and all of the egg yolks in the well and add the water. Beat the eggs and water together using a fork.
Start pulling the dry ingredients into the wet until a dough begins to form.
Knead the dough for 7-10 minutes or until firm but silky to the touch.
Tightly wrap the dough in plastic warp and let sit at room temperature for 1 hour.
Unwrap the dough and divide into eighths.
Using a KitchenAid pasta attachment, roll each section of the dough to the second to last setting (#7 on my attachment). Handle the dough with care - it will tear very easily.
Brush half of each strip of pasta with the remaining egg, lightly beaten. Arrange the parsley leaves on top of the egg wash and fold the untouched half of the pasta over top. Run your hands firmly over top of the pasta to force any air out and to create a seal. Trim any rough edges and cut the pasta into 3x5-inch rectangles. Dust with flour and set aside until ready to cook.
