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. Turn the heat up, add the mushroom melt, and cook until deeply browned and aromatic.
4. Fold in the mayonnaise and season generously; give everything a minute to come together.
5. Pour in the vegetable stock, bring to a gentle simmer, and cook until thickened and glossy.
6. Taste and adjust, then finish with toasted nuts right before serving.
7. Serve warm, ideally with something to soak up the sauce.
