Heat a non-stick frying pan over medium heat. Cook the pancetta, stirring, for 3-5 minutes or until crisp and golden. Set aside to cool slightly.

Place onion in a food processor and process until finely chopped. Add pancetta, basil, parmesan, mozzarella and oats. Process until well combined. Add mince, egg and 115g (1⁄2 cup) pasta sauce. Pulse until just combined. Place mixture in a large bowl and toss through pasta. Place mixture on prepared tray. Shape into a 12 x 34cm log. Bake for 1 hour or until cooked through.
