Making the rigatoni chips: Cook the pasta in salted boiling water until partially cooked (about half the recommended cooking time) and drain. Heat the canola oil in a deep-fryer or a heavy-bottomed pot to 350 degrees F. Deep-fry the rigatoni in several batches until crisp and golden. Remove with a slotted spoon and drain on a wire rack. Sprinkle with sea salt.
Making the herbed filling: Over medium heat, saute the garlic in the olive oil until slightly golden, about 30 seconds. Remove from the heat immediately and transfer to a medium bowl to stop the garlic from burning. Add the cheeses and oregano and blend until smooth using a rubber spatula. Season with sea salt and pepper. Transfer the filling to a piping bag fitted with a small straight tip. Fill each "chip" with the herbed filling and serve.
