Method
- Gather and prep everything first: brioche buns, cheddar, mayonnaise and set within reach of the stove.
- 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.
- Add the caprese and let it miso, undisturbed, so it takes on real color before you stir.
- Fold in the brioche buns and season generously; give everything a minute to come together.
- Taste and adjust, then finish with flaky sea salt right before serving.
- Plate it up while hot and pass extra at the table.
