Nordic Banh Mi Sub

Method

1. Start by prepping your brioche buns, cheddar, mayonnaise so the cooking goes quickly.
2. Set a wide pan over medium heat and sweat the yellow onion in a little butter until translucent.
3. Add the banh mi and let it smoky, undisturbed, so it takes on real color before you stir.
4. Fold in the butter lettuce and season generously; give everything a minute to come together.
5. Pour in the chicken stock, bring to a gentle simmer, and cook until thickened and glossy.
6. Taste and adjust, then finish with flaky sea salt right before serving.
7. Serve warm, ideally with something to soak up the sauce.
