Step 1

Heat the oil in a large pan. Add the onion and cook for 5 mins until soft, then add your chosen veggies and continue cooking for another 5-10 mins or until tender. Add the leftover meat, the rice and beans, along with the sauce from the can. Stir everything together and cook for 5 mins until piping hot.

Step 2

Heat another frying pan, or a griddle pan, until hot, and heat oven to 140C/120C fan/gas Now assemble the burritos. Warm a wrap for 10 secs on the hot pan (keep the pan hot, you’ll need to use it again).

Step 3

Pile roughly a sixth of the rice mixture onto the centre of the wrap. Top with a little avocado and some cheese, then brush beaten egg around the edge. Fold the ends over the filling, then fold in the sides, like an envelope.

Step 4

Flatten a little to a parcel, then place, seam-side down, in the hot pan. Cook for 2 mins until the underside has sealed shut and is toasted a golden brown, flip over and cook for a few mins more.

Step 5

Keep the burrito warm in the oven while you continue assembling and cooking the remaining burritos. Serve with soured cream, if you like.
