This delicious quiche is unlike any we’ve ever come across before! Sweet potato is the star of the show with plenty of caramelised onion and fresh basil added to the mix.
The mustard and brown sugar sauce really takes things to the next level and bring a whole new flavour to the dish. You can make your own pastry from scratch if you prefer, but simple store-bought shortcrust pastry will do the trick.
This incredible recipe is great on its own or paired with a fresh salad for lunch or dinner.
