Aegean Steak Panini

Method

1. Start by prepping your brioche buns, cheddar, mayonnaise so the cooking goes quickly.
2. Warm a splash of olive oil in a heavy pan over medium heat, then add the yellow onion and cook until soft and fragrant, about 4 to 5 minutes.
3. Turn the heat up, add the steak, and cook until deeply browned and aromatic.
4. Stir in the pickles along with a good pinch of salt, scraping up anything stuck to the bottom of the pan.
5. Pour in the chicken stock, bring to a gentle simmer, and cook until thickened and glossy.
6. Taste and adjust, then finish with a handful of herbs right before serving.
7. Plate it up while hot and pass extra at the table.
