Method

1. Heat the oil in a large pan. Add the chopped onion and cook for 5 minutes until soft, then add your chosen veggies and continue cooking for another 5-10 minutes or until tender. Add the cooked chicken, rice and beans. Stir everything together and cook for 5 minutes until piping hot.
2. Heat another frying pan, or a griddle pan, until hot and heat the oven to 140ºC. Warm a wrap for 10 seconds on the hot pan. Keep the pan hot as you'll need it again.
3. Pile roughly a sixth of the rice and chicken mixture onto the centre of the wrap. Top with a little avocado and some cheese, then brush beaten egg around the edges of the wrap. Fold the ends over the filling, then fold in the sides like an envelope.
4. Flatten a little to a parcel, then place, seam-side down, in the hot pan. Cook for 2 minutes until the underside has sealed and is toasted a golden brown. Flip over and cook for a few more minutes.
5. Keep the burrito warm in the oven while you continue assembling and cooking the remaining burritos.
