In a large mixing bowl, combine the flour, eggs, olive oil, and salt for the pasta dough. Mix until a crumbly dough forms.
Turn the dough onto a floured surface and knead for about 5 minutes, or until smooth and elastic. Cover with plastic wrap and let it rest for 30 minutes.
In the meantime, prepare the filling. In a skillet, cook the sausage over medium heat, breaking it into small pieces. Cook until browned and cooked through. Remove from heat and let it cool.
In a separate bowl, combine the cooked sausage, ricotta cheese, Parmesan cheese, parsley, salt, and black pepper for the filling. Mix well.
Roll out the rested pasta dough into thin sheets using a rolling pin or a pasta machine. Cut the dough into 3-inch squares.
Place a spoonful of the filling in the center of each square. Moisten the edges with water and fold over to form a triangle. Press the edges firmly to seal the ravioli.
Bring a large pot of salted water to a boil. Cook the ravioli in batches for about 3-4 minutes, or until they float to the surface. Remove them with a slotted spoon and set aside.
To prepare the pesto sauce, combine the basil, Parmesan cheese, pine nuts, and garlic in a food processor. Pulse until coarsely chopped. Slowly drizzle in the olive oil while the processor is running. Season with salt and pepper to taste.
In a large serving bowl, toss the cooked ravioli with the pesto sauce until well-coated. Serve with grated Parmesan cheese and fresh basil leaves on top.
