Ingredients
Directions
Prepare
Fry the slices of beef gently in a little butter, being careful not to dry them out.
Lay the beef on a flat dish and cover with fried greens.
Boil the greens until tender, then drain and mince them.
Cook and serve
In a frying pan, heat the minced greens with butter, sliced onion, pepper, and salt until hot.
Serve when the onion is cooked.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cold boiled beef
- Provides the meaty base; gentle frying keeps it moist and tender.
- Butter
- Adds fat and richness, helping the beef and greens brown and taste savoury.
- Cabbage
- Forms the bulk of the dish, giving texture and mild flavour once cooked.
- Onion
- Adds sweetness and aroma as it softens and cooks in the pan.
The step that matters
Fry the beef gently. High heat dries out lean cooked meat, making it tough. Gentle frying in butter keeps the slices moist and tender.
