In a large bowl, whisk together the flour and salt.
Make a well in the center of the flour and add in the eggs all at once.
Mix them together well with your hands, adding in the olive oil and knead the dough for 5 minutes.Form into a ball and leave in the bowl, covered with plastic wrap for 30 minutes.
There are two methods – run a small piece through a pasta machine a few times or use a rolling pin and some flour to create a thin sheet. Cut circles out of the dough using a cookie cutter or a glass.Place 1 teaspoon of chosen filling in the center of half the circles.
Lightly brush egg wash around the edge of the circle and then place the second circle on top over the filling, using a fork to crimp the edges all around.
Continue with remaining pasta dough until all the dough or filling has been used.
To cook the pasta, bring a large pot of salted water to a boil. Add ravioli and cook for 2-3 minutes. Once they float to the top, it is done. Drain pasta and toss with olive oil or sauce.
