Cut the chicken into small pieces and add onion, garlic, salt, black pepper, oil, butter, and mustard. Let it marinate in the fridge for an hour.

Then, cook it over low heat until the onion releases its juices. If it's not fully cooked, add a little water.

Once cooked, add the cooking cream and let it thicken. When ready, set it aside to cool.

Take the chicken, add the corn and lettuce, and stuff the batbout with this mixture.

Enjoy your meal!
