To prepare the dough: mix yolks and both flours in stand mixer with dough hook until compact and smooth. Cover bowl with a towel and let rest for 1 hour in refrigerator.
To prepare the filling: mix chopped chicken with the Parmesan, extra virgin olive oil, and oregano. Add salt and pepper to taste and transfer the mixture to a pastry bag.
To prepare the sauce: Melt the butter with the water and whisk together until it emulsifies and has a creamy texture. Add the chopped herbs and keep warm.
Remove pasta dough from the refrigerator and use a pasta rolling machine to make very thin layers of pasta. Stuff the ravioli in your preferred shape. Cook in boiling, salty water (2 quarts water with 2 tablespoons of salt) for 4-6 minutes.
Put the cooked ravioli in a sauce pan with the herb sauce, and cook 1 minute over very high heat.
Divide the ravioli into 4 pasta bowls and garnish with the fresh shiso leaves.
