A stir-fry with toothsome potato and celery. Seasoned with grainy mustard, mayo, and soy sauce. Even with wiener sausages. Also great to pack in bentos.
I love celery. Because its leaves are also tasty and fragrant, I stir-fried them with some potatoes, and seasoned with mayo and soy with grainy mustard as an accent.
You could also use bacon or fish sausages instead of wiener sausages.
